MORE INFORMATION
Option Definition
------ ----------
/A Creates a listing of the disassembled object code for each
source line and shows the assembly-language code generated by
the compiler.
/Ah Allows dynamic arrays of records, fixed-length strings, and
numeric data to occupy all of available conventional memory.
If this option is not specified, the maximum size is 64K per
array. Note that this option has no effect on the way data
items are passed to procedures. (See also the REM $DYNAMIC
metacommand.)
/C:<n> Sets the size (<n> = bytes) of the buffer receiving remote
data using an asynchronous communications adapter for each
communications port. (The transmission buffer is allocated 512
bytes for each communications port and cannot be changed on
the BC command line.) This option has no effect if the
asynchronous communications card is not present. The default
buffer size is 256 bytes total for BOTH ports; the maximum
size is 32,767 bytes. The default, /c:512, is automatically
added when invoking the Make EXE File command from the Run
menu in QuickBasic 4.0b and 4.5 (not in QuickBasic 4.0).
/D Generates debugging code for run-time error checking and
enables CTRL+BREAK. This option is the same as the Produce
Debug Code option from the Run menu Make EXE File command
within the environment.
/E Indicates the presence of ON ERROR with RESUME linenumber
statements. (See also the discussion of the /x option in this
list.)
/MBF Causes the QuickBasic conversion functions to treat
IEEE-format numbers as Microsoft binary format numbers. The
intrinsic functions MKS$, MKD$, CVS, and CVD are converted to
MKSMBF$, MKDMBF$, CVSMBF, and CVDMBF, respectively. See
the "Microsoft QuickBasic 4.0: Basic Language Reference"
manual or corresponding Help for more information about these
functions.
/O Substitutes the appropriate BCOMxx.LIB stand-alone program
library for the BRUNxx.LIB run-time module library.
/R Stores arrays in row-major order. Basic normally stores arrays
in column-major order. This option is useful if you are using
other language routines that store arrays in row order.
/S Writes quoted strings to the object file instead of the symbol
table. Use this option when an "Out of memory" error message
occurs in a program that has many string constants.
/T This option is for terse. It suppresses warning messages
during compilation. However, severe error messages still are
displayed. This option is not available in QuickBasic 4.0.
Also, /t is automatically added to the BC command line in
QuickBasic 4.0b and 4.5 whenever you choose the Make EXE
File command from within QB.EXE.
/V Enables event trapping for communications (COM), light pen
(PEN), joystick (STRIG), timer (TIMER), music buffer (PLAY),
and function keys (KEY). Use this option to check between
statements for an occurrence of an event.
/W Enables event trapping for the same statements as /v, but
checks at each line number or label for occurrence of an
event (thus /w does less-frequent checking than /v).
/X Indicates presence of ON ERROR with RESUME, RESUME NEXT, or
RESUME 0.
/Zd Produces an object file containing line-number records
corresponding to the line numbers of the source file. This
option is useful when you want to perform source-level
debugging using the Microsoft Symbolic Debug Utility (SYMDEB)
available with Microsoft Macro Assembler version 4.0.
/Zi Produces an object file containing debugging information used
by the Microsoft CodeView debugger, available with Microsoft C
version 5.0, Microsoft Macro Assembler version 5.0, and
Microsoft Basic Compiler version 6.0.
The following BC.EXE options are supported in Microsoft Visual Basic
for MS-DOS, version 1.0; in Microsoft Basic Compiler for MS-DOS,
versions 6.0, 6.0b; and in Basic PDS for MS-DOS and MS OS/2, versions
7.0 and 7.1, but not in QuickBasic for MS-DOS, versions 4.0, 4.0b, or
4.5:
/Lp Creates a protected-mode object file for use in MS OS/2
protected mode, no matter which operating system you are in at
compile time.
/Lr Creates a real-mode object file for use in MS-DOS or MS OS/2
real mode (MS-DOS 3.x box), no matter which operating system you
are in at compile time.
/FPi Generates in-line (i) coprocessor instructions for floating
point (FP) math. If a coprocessor is not present at run time,
the Basic run-time system will emulate a coprocessor.
/FPa Generates code using alternate (a) math library, which runs
faster than emulating a coprocessor when none is present.
The following BC.EXE options and features added in Visual Basic for
MS-DOS, version 1.0; and Basic PDS for MS-DOS, versions 7.0 and 7.1 are
not found in earlier versions:
/Es Allows you to share expanded memory between Basic and
mixed-language routines that make use of expanded memory.
Specify /Es when you are going to use a mixed-language routine
that makes use of expanded memory.
/Fs Enables you to store string data in far memory.
/G2 Generates instructions specific to the 80286 processor chip
that result in smaller, faster executable code.
/Ot Optimizes the performance of procedure calls.
/Ib:x Increases the amount of conventional memory reserved for
ISAM's buffers. The x here represents pagebuffers and defaults
to 6 for PROISAM and 9 for PROISAMD. Maximum number for x is
512.
/Ie:x If you have expanded memory, ISAM will automatically use up to
1.2 MB of it for its buffers. ISAM takes as much EMS
memory as possible by default, which increases conventional
memory as well as improves performance. The x in this case
represents the amount of EMS memory to reserve.
/Ii:x Specifies the number of non-NULL indexes used in the program.
Use this option if your program has more than 30 indexes. The
x stands for indexes.
In Visual Basic for MS-DOS, version 1.0; and Basic PDS for MS-DOS
versions 7.0 and 7.1, the MS-DOS INCLUDE environment variable
enables you to determine where BC.EXE will look for included files
without changing the $INCLUDE metacommand in your source file.
In Visual Basic for MS-DOS, version 1.0; and Basic PDS for MS-DOS
and MS OS/2, version 7.1, the following options were added for BC.EXE:
/? or /Help Displays compiler syntax and options.
/FBr[filename] Generates a file containing restricted program symbol
information for use with the Programmer's WorkBench
(PWB) Source Browser. This information file has the
name specified by the "filename" argument. If no name
is specified, it has the same name as the source file
with an .SBR filename extension. The file contains
information about the definitions and references to
all global symbols.
/FBx[filename] Generates a file containing extended program symbol
information for use with the Programmer's WorkBench
Source Browser. This information file has the name
specified by the "filename" argument. If no name is
specified, it has the same name as the source file
with an .SBR filename extension. The file contains
information about the definitions and references to
all global and local symbols.
The information for the /Z option applies to PWB, as
well as to the M editor.
Visual Basic for MS-DOS, version 1.0 maintains the same compiler
switches as Basic PDS for MS-DOS, version 7.1 with the following
exceptions. The /Lp, /Lr, /FBr, /FBx, and /Fs switches have all been
eliminated. The /G3 switch has been added. Listed below is a
description of the /G3 switch:
/G3 Generates instructions specific to the 80386
processor which potentially results in smaller and
faster executable code.
