OpenVMS ALPBASR03_062 Alpha V6.2x BASIC Run-Time Library ECO Summary

TITLE: OpenVMS ALPBASR03_062 Alpha V6.2x BASIC Run-Time Library ECO Summary
 
Modification Date:  18-MAY-1999
Modification Type:  New Kit
                    This kit supersedes ALPBASR02_070 for 
                    OpenVMS Alpha V6.2x only.

NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for DEC$BASRTL.EXE OpenVMS Alpha V6.2 through 
V6.2-1H3.  This kit addresses the following problems: 

Problems address in ALPBASR03_062:

  o  The BASIC function DATE$() formats the year as only two
     digits.

  o  An incorrect SCAFACINT message appears when ASTs are used.

  o  A BASIC output routine, when run in BATCH, does not properly
     account for international characters (high-bit-on).  This
     problem causes a variety of strange output, depending on how
     many such characters are being printed.  For example, if the
     command

       PRINT STRING$(999%,ASCII("é"))

     is run in batch (BASIC V3.4), the error "%BAS-F-MEMMANVIO,
     Memory management violation" occurs.

  o  Under DEC BASIC with DEC$BASRTL V01-017, error #35, "Memory
     Management  Violation", is incorrectly issued when a second
     open statement is used to connect an I/O stream to a remote
     file already opened.  The correct error would be error #12,
     "Fatal System I/O Failure".

     Below is an example for a file to be opened twice over the
     network, so that a secondary access to the same data is
     created.

     Assume that "ixfile" is a logical name defined to point to a
     file on another node.  The second open statement returns BASIC
     ERR=35, which cannot be trapped, so the program must abort.

       MAP (ixfile) STRING the_item

       ! First, create a sample file.
         OPEN "ixfile" FOR OUTPUT AS FILE #1, INDEXED FIXED, &
                       PRIMARY KEY the_item, MAP ixfile
       CLOSE #1

       ! Open the newly created file.

       OPEN "ixfile" FOR INPUT AS FILE #1, INDEXED FIXED, &
                     ACCESS READ, ALLOW MODIFY, MAP ixfile

       !  Attempt to open the same file and connect an I/O stream  to
          the remote file !  already opened (ERR=35 will result)

       OPEN "ixfile" FOR INPUT AS FILE #2, INDEXED FIXED, ACCESS &
                     READ, ALLOW MODIFY, MAP ixfile, CONNECT #1

  o  Under some conditions, a traceback list from a fatal error in
     a DEC BASIC program indicates some incorrect line numbers.

     Also, certain I/O failures report the wrong error code due to
     an I/O error recovery problem.

     NOTE:

       In order to get the full effect of this fix, the 
       ALPTRAC02_062 kit should be installed.


Problems addressed in ALPBASR02_070 for OpenVMS Alpha V6.2x:

  o  A BASIC program may ACCVIO or hang in an infinite loop in
     DEC$BASRTL if AST calls a BASIC routine.


Problems addressed in ALPBASR01_070:

  o  The last build got a link warning from another facility.


Problems addressed in ALPBASR02_062:

  o  Did not properly account for linked chain of XABs, some of
     which needed virtual memory to be freed.


Problems addressed in ALPBASR01_062:

  o  Matrix multiply of D-Float types always produces integer
     results.

  o  The lib$signal of an error produced a fatal and aborted
     program, preventing other handlers' recovery.

  o  Lib$signal caused program to lose  local  dynamic  store,  and
     execute incorrect code.


INSTALLATION NOTES:

The system does not need to be rebooted after this kit is installed.
However, if you have other nodes in your OpenVMS VMScluster, they 
should be rebooted or you should install this kit on each system in
order to make use of the new image(s).
