        JASON's TERSE MANUAL for
        JASON's LOW-BUDGET SURVEY-PROGRAMS



        A good user's manual for these programs would be far more difficult
        for me to write than the programs themselves and it would be 
        equally time consuming.  This is why I've only provided this terse
        manual.  Sorry it's not lucid.

        About these programs:

        There is nothing fantastic about these programs.  There is no 
        excellent interface.  They aren't riddled with all sorts of fancy
        features.  There is no hacker level coding here.  There is only 
        basic solid solutions to time honored scenarios.  In fact I may
        even be taking a step backwards with the way I've programmed the 
        48, but what I've created is not too slow or too difficult to use
        and understand.  I bring back the simplicity of an older calculator
        with the advantage of a big screen display.  In addition, because 
        almost everything is a function, you are almost always in stack 
        mode and can therefore use the 48 as a calculator.  There is no 
        need to carry a second calculator.

        If you are a serious surveyor, you had better get the card.  This 
        is no substitute.  However, these programs solve for some things 
        the card doesn't, and in some cases it solves for some things in an
        easier manner than the card does.  In my limited opinion, I believe
        my set of programs to be a good augmentation to one of those
        main-stream cards.

        *******************************************************************
        *******************************************************************

        Getting started:

        I believe that these programs will run in both the SX and GX series.
        However, I cannot say for sure.  Actually, they should even run in 
        the S and G versions provided you have enough memory.  Again, I 
        could not say for sure as I no longer have these test vehicles.  
        I've only tested them on the GX.

        I've provided four files including this one.  They are: TERSEMAN.TXT,
        JASON1, JASON2 and JASON3.  TERSEMAN.TXT is this file.  JASON1 is for
        the GX.  It requires thirty-something kilobytes to load and at least 
        a couple of kilobytes to run.  The difference between this file and 
        JASON2 is that it uses the GX's SORT library routine in the filing 
        utility.  The file JASON2 is for the SX with enough RAM.  It requires
        as much as JASON1 but unlike JASON1, it can run in the SX as well as
        the GX.  JASON3 should run in any version of the HP-48 provided there
        is enough memory.  This file does not have the file utility and
        unless you are fairly acquainted with what I've done, this could be a

                                                                          3

        pain.  Anyway, if this is the way you go then this file will leave a
        small file for you to store and retrieve coordinates in, and it's in
        the directory you downloaded it as (JASON3).  This is very important 
        to know as you have to be in this directory to access it via [STOPT] 
        and [RCLPT].  To get started, follow these instructions.


              JASON1 - for the GX
              JASON2 - for the GX or SX with enough free RAM
              JASON3 - for any of the 48s that have enough free RAM
            TERSEMAN - this file



        I. Download the appropriate file to your calculator.  I assume that
           if you were resourceful enough to acquire these files, you 
           should be resourceful enough to figure out how to do this.  
           Otherwise read the chapter in your manual on file transfers and
           Kermit.
   
        II. Now get into the directory you downloaded (should be JASON1, 
           JASON2, or JASON3) .  Press [VAR] to check out which key to 
           press.  Once you are in this directory, look for the |INSTA|
           menu key andpress it.  The calculator should think for a while
           and then go off.
   
        III. When you power the calculator on, all you need to do is engage
           the USER mode and you're set.


        These programs make use of the USER defined keys.  They work almost
        exclusively on this principal.  [CST] has been defined as well and 
        so to access your regular custom menu, just disengage the USER 
        defined keys before pressing [CST].

        You should be able to run from any normal directory in the 48.  The
        coordinate files accessed by the corresponding programs will be the
        ones in directory you are currently logged into.  Look in the upper
        left hand corner in the curly brackets to see what directory you're
        in.  Please appreciate this.  I have spent a lot of time and effort
        in perfecting this feature.  I have sacrificed speed and resistance
        to operator errors in doing so.  Be weary when changing directories.

        [CST] is the key to your so called main menu.  Press this key to
        access the programs described later in this file.

        *******************************************************************
        
                                                                          4
        *******************************************************************

        Generalities:

        I. If you don't have any variables anywhere the with same names as
           the ones placed in the HOME directory by this program, there 
           should be no problem in running these programs in any directory.
           This program may or may not place the variable CURRENTFILE in
           whatever directory you are working in.  It's not recommended that
           you use this variable name anywhere.
   
        II. Most of the programs requiring an angle or an azimuth take them 
           in D.MS format.  The obvious exception is the ->HMS function.  
           Also, when an angle or azimuth is returned, it is also in the 
           D.MS format, the obvious exception being HMS->.
   
        III. When a coordinate is asked for, it is to be in the form 
           (North, East) in level 1 of the stack or the North component in 
           level 2 of the stack and the East component in level 1 of the
           stack.
   
        IV. When a distance is called for, it is to be a Horizontal 
           Distance.  When a distance is returned from a function, it is also
           in a Horizontal Distance unless otherwise specified.
   
        V. When defining a curve and rotation is important, entering the 
           radius as a negative value will denote a left hand curve and a 
           positive radius denotes a right hand curve.  A tip-off to this is 
           the menu key |RD/RO| (Radius/Rotation).
   
        VI. When you see the four menu keys |INCR| |STA-| |STA+| |STA->| on
           the same menu page, their meaning is this.
   
           A. |INCR| enters the amount to advance or regress the station 
              solved for with the sub-menu it is in.
      
           B. |STA-| solves the current program for the station regressed 
              by the increment entered by |INCR| and started off by |STA->|.
      
           C. |STA+| solves the current program for the station advanced by 
              the increment entered by |INCR| and started off by |STA->|.
      
           D. |STA->| solves for whatever the program solves for with 
              respect to whatever station is entered by this key.  It also 
              initiates the station to be advanced or regressed by prior
              described menu keys.

                                                                         5

              Example:  Say that you were solving for the Superelevation 
              from 3 + 00 to 4 + 00 every twenty-five feet, assuming that 
              you have already set the parameters of the diagram, you could
              do something like this:
           
                  25 |INCR|
                  300 |STA->|
                  |STA+|
                  |STA+|
                  |STA+|
                  |STA+|

        VII. The parameters of most of the programs are static variables
           and remain in force until you change them.  Check it out, you
           don't need to keep on reentering the same setup every time you
           run these things, just view the setup to verify.  Also, there
           is no particular order in which you need to enter them and you
           only need to enter the ones you wish to change.
   
        VIII. When the menu key |VIEW| is pressed, it reveals the 
           parameters of whatever program sub-menu you are at.

        IX. Don't use the user flag 2.  My programs use it as a red flag 
           and won't run properly if you use it.  If it appears when 
           running a program of mine, it means that it bombed out.  Either
           run another program that won't bomb out (VIEW something), or 
           under the |UTIL| menu run |INIT| which will reset your flags and
           re-initialize the USER defined keys that I programmed.
   
        X. Some of the programs in this set of programs will leave the 
           results of whatever was solved for on the top of the stack for
           possible use elsewhere.  Pressing the [ON] button will update 
           the stack display and you will be able to see this.

        Note: Examples are done with a South oriented azimuth.

                                                                          6
        *******************************************************************

        The USER defined keys:

        There are twelve (12) of them that I defined.  You may wish to
        consult your owner's manual if you don't know what I'm talking 
        about.  From here on, [<-|] and [|->] means left-shift and 
        right-shift respectively.  Buying a keyboard overlay is highly
        recommended, but cutting up POST-IT notes and pasting them in the 
        appropriate place works well also.


        I. PRINT MODE is toggled on and off by the first key in the second 
           row.  This is [MTH] on GX.  When PRINT MODE is on the 48 will 
           send output to the IR port for the IR printer to provide you 
           with an audit trail to check your work.
   
        II. FIX is a pain in the butt to get to so I've assigned it to the
           third key in the fifth row.  This is [EEX] on the GX.  Enter the
           number of decimal places you would like the 48 display set at 
           and then press this button.
   
        III. RCLPT is assigned to the second button in the second row.  
           This is [PRG] on the GX.  This recalls a point to the top of the
           stack. This is very useful to learn how to use.  Enter the 
           number of the desired point and press this button.  Note that an
           elevation is displayed for a recalled point.  It is purely for 
           annotation purposes with my programs and can be changed with the
           STOEL USER defined key.  Actually, I made the file format like 
           this so I could swap files with my partner.
   
        IV. STOPT is assigned to the second key in the third row.  This is
           [STO] on all of the 48s.  This is a very important key to know. 
           If a coordinate (as discussed in generalities) is sitting on the
           top of stack enter the number of the point you wish to store it
           as and then press [STO].  It is now stored under that number if
           all went right. Try recalling it.
   
              Example:  Say that you wanted to store the coordinate 
              123N 456E as point number 7, then one way to store this
              coordinate could be these keystrokes:

                 123 [ENTER]
                 456 [ENTER]
                   7 [STOPT]
         
              Say this coordinate is the result of some program that leaves
              a coordinate as a result on the top of the stack.  Then this 
              coordinate is already sitting on top of the stack in the form
              (123, 456) and to store it as point #7 the following 
              keystrokes should work:
      
                   7 [STOPT]
      
              Anyway, play with it and figure it out.

                                                                          7

        V. STOEL is assigned to the third key in the third row.  This is
           [EVAL] on the GX.  It takes an elevation from level 2 of the 
           stack and the point number in level 1 of the stack and stores it
           appropriately.

        VI. [CST] has a little program assigned to it which should be 
           almost invisible to anyone not paying close attention.  Use it
           just like you normally would.  It brings out the "main" menu
           which is described under The Custom Menu.  If you have a CST
           variable and want to access it with [CST] then disable the USER
           defined keys.

        VII. Six of the defined keys deal with the H.MS format.  
           [<|] & ( [+] or [-] or [*] or [/] ) (such poor English), will
           perform the regular functions of addition, subtraction,
           multiplication, or division entirely in H.MS format.  This is to
           say that they will take their operands in H.MS format and return
           the result in H.MS format.  [<-|] [0] will take an operand in 
           H.MS format and put it in decimal degrees format.  [<-|] [.] 
           will perform the opposite function of taking an operand in 
           decimal degrees format and converting it to D.MS format.

           These functions have a variety uses, especially when checking
           plans or figuring out an azimuth.

              Exmple: Say that you want to subtract 45-30-00 from 50-00-00
              you could do so with these keys.

                 50 [ENTER]
                 45.30 [<-|] [-]

              The answer of course is 0.30 (30 minutes).

        *******************************************************************

                                                                          8
        *******************************************************************
   
        The Custom Menu:

           |EART |     |     |     |ABOUT|UTIL |   [NXT]
           |INVER|TRAV |AZ/AZ|AR/LI|AR/AR|RADIA|   [NXT]
           |LINEA|CONV |CURVE| VC  | SLG |SUPER|   [NXT]

        There are fifteen menu keys accessed with [CST] fourteen of these 
        are sub-menus.  |ABOUT| just displays something neat.  The fourteen
        sub-menus let you solve those things you would like to figure out.  
        What follows is a brief description of those sub-menus.  From here
        on TFTOSAS means "Takes From Top Of Stack And Stores", and if you
        substitute that phrase in when you see it, it may make more sense 
        as you read along.

        I. |INVERS| "Inverse Azimuth" solves for the azimuth and distance 
           from point A to point B.
   
           A. |PT A| TFTOSAS a coordinate as point A.
      
              Example: To enter 123N 456E as point A one could key in

                 123 [ENTER]
                 456 |PT A|
       
              Or say you previously stored this coordinate as point #7
              you could have recalled it to the top of the stack and done
              the same thing using:
       
                   7 [RCLPT]
                   |PT A|
         
           B. |PT B| TFTOSAS a coordinate as point B.
      
           C. |SOLVE| Solves for the azimuth and distance.
      
        II. |TRAV| "Traverse"
   
           A. |Z&S->| converts a Zenith angle in level 2 and a Slope 
              Distance in level 1 to a Horizontal Distance and a Vertical 
              Distance.  There is no display screen.  This is sometimes 
              useful for reducing notes.
      
           B. |POINT| TFTOSAS a coordinate to calculate from, 
              the "Occupied Point."

           C. |HD2TL| same as | SIDE | except that it makes the resulting 
              point the new "Occupied Point."  Like "Head To Tail" when 
              talking about vectors.
      
           D. |SIDE | takes an azimuth from level 2 and a distance in 
              level 1 and solve for the resulting point from the
              "Occupied Point."

                                                                          9

                 Example:  Say you wanted to start at the coordinate
                 (100, 100) and from there you went the direction
                 123-45-12 and distance 52.14 (not a side shot).

                     100 [ENTER]
                     100 |POINT|
                     123.4512 [ENTER]
                     52.14 |HD2TL|           answer: 128.9700 N
                                                      56.6489 E

                 The resulting coordinate is solved for and left on the
                 top of the stack for possible use elsewhere (like for
                 storing) and it is also made the new point to "shoot"
                 from.  Now say you wanted to calculate several
                 coordinates from this new point "side shots", use the
                 |SIDE | key.  Let's try 45-45-45 100 and 74-18-19 361.

        VIII. |CONV | "Coordinate Conversion" converts coordinates formed 
           in one system to their counterpart in another system.  As
           parameters the coordinates on two points (the same two) in both 
           systems need to be known.  If you have a definite scaling
           factor, then enter it.  If you don't, then set the scaling 
           factor to zero and a reasonable one will be calculated for you.

           D. | NEW2 | TFTOSAS coordinate of point 2 in new system.

           E. |SCALE | TFTOSAS a scaling factor.  If the unit in the old 
              system were the foot and the unit in the new system were a 
              yard then the scaling factor would be 3.  Setting the 
              scaling factor to 0 will let the program figure out the scale
              itself.  If you do this then scaling factors very close to 1 
              will be forced to be 1.

           G. | BLOC | converts a block of contiguous points in the current

              For a left hand curve, the full delta is at the PC station 
              and 0 degrees is at the PT station.  This is useful with 
              instruments that measure angles only in one direction.
      
        X. | VC  | "Vertical Curve" solves for elevations along a
           vertical curve.  For areas outside of the curve, the solution
           taken as though on the tangent to the curve.  The more precisely
           one enters the elevation parameters, the more reliable the 
           answer will be farther away from the curve.

                                                                         13

           K. | STA->| f(STA)=Superelevation
      
        XIII. |EART | "Earthwork" this program does some basic end area and
           volume computations.  The area solution is my rendition of the
           old Double Meridian Distance thing.  The volume is probably only
           useful if you have to fill out the same earthwork form that I 
           do.  I have a spreadsheet that takes care of these computations,
           but I'm not always afforded access to a PC or a printer.  Sorry
           if it seems useless, but I thought I'd leave it in anyway.

           The first two menu keys are for area computation and the last 
           four pertain to volume computation.  This is one of the only 
           programs with units directly attributed to it.
   
           To find an area with this, it is done using the old "DMD" 
           technique.  You basically start with a point on the perimeter 
           and travel along the perimeter entering every breakpoint along
           the way.  When you come full circle and reach the point you 
           started at, the area is revealed.

              Example:  You have an area bounded by the points
              (0 0) (1 2) (6 5) (0 0) the area is 3.5.  To find
              this with the programming at hand, these are the
              keystrokes:

                 0 [ENTER] 0 |START|
                 1 [ENTER] 2 |NEXT |
                 6 [ENTER] 5 |NEXT |
                 0 [ENTER] 0 |NEXT |                                                                     pg 14

                                                                        15

           Recalling coordinates to the top of the stack and entering them
           with |START| and |NEXT | will also work and is useful for 
           finding areas of lots and things.
   
           Finding the volume of some earthwork thing like excavation or
           embankment using the old end-area method is what the last four
           keys are geared for.  Like I said, this was created for those 
           of us that had to fill out that Department of Transportation 
           form.  Try these keystrokes and you should understand how and 
           what it does.  This works good with a printer.
   
              |RESET|
              100 [ENTER] 200 | S&A-> |
              150 [ENTER] 250 | S&A-> |
              200 [ENTER] 151 | S&A-> |
              |TOTAL|
      
           Keep in mind that rounding takes place at various places.  
           Experiment and observe.
   
           A. |START |
      
           B. |NEXT  |
      
           C. | L/S  | toggles you between using the long and short form 
              for calculating earthwork volume.
      
           D. |RESET | resets the volume quantity to zero.
      
           E. |TOTAL | recalls running total volume to stack and displays.
      
           F. | S&A->| takes station and area at station from stack and 
              displays appropriate calculations (end area method).

        XIV. | UTIL | "Utility functions"
   
           A. | FILES| interactive screen that works with JASON's files.  
              May not be installed.  Use this to select and create and
              delete coordinate files.  Sorry, I never figured out how to
              engage the alpha-lock with a program.
      
           B. | BOOST| takes a number from the top of the stack and boosts
              the current file by that many points if possible.
      
           C. | INIT | re-initialize the USER defined keys and flags.  Sets
              the USER keys flag.

           E. |  N/S | toggles coordinate system between North and South 
              azimuth.
      
           F. | VIEW |

        *******************************************************************
        
        Miscellaneous:

        This set of programs is in the form of a library object.  Its
        ROMID is 1013.  The installation program stores the library object
        to port 0.  If for some reason you would like to store and run
        this library object from port 1 or port 2 (if you have a RAM card),
        I believe you can.  Again, I can't tell you for sure.  I never
        tried.  However, you can try.  Just recall the object to the stack
        and store it in one of the other ports.

        You may wish to purge the library.  If so, then I recommend that
        you warm start the system first.

            [ON] + [C]

        When the system comes back to life, try these keystrokes:

            [|->] [+]
            [0] [|>]
            1013 [ENTER]

        you should see :0:1013 on the stack or something very similar
        depending on the display setting.  Next get to the HOME
        directory and detach and purge the library.

            [ENTER]
            [alpha] [alpha] DETACH [SPC] PURGE [ENTER]

        That should have done the job.
