TITLE: OpenVMS VAXBASR01_071 VAX V7.1 BASIC Run-Time Library ECO Summary

Modification Date:  19-MAY-1999
Modification Type:  New Kit

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 the BASIC RTL on OpenVMS VAX V7.1.  This kit 
addresses the following problems: 

  o  An indexed file open failed and it could include loss of
     memory.

  o  No error occurred for strings with characters having the high
     bit on.  Some examples are:

       PRINT INTEGER("123")
       PRINT INTEGER("éä")
       PRINT INTEGER ("efg")

     In the above example, only the first line will not result in
     an error.  This first PRINT command converts the characters
     (number 123) into the integer 123.

     The third PRINT gives the following error because the
     characters do not look like a number:

       %BAS-F-ILLNUM, Illegal number
        -BAS-I-FROMOD, In module NONAME

     Finally, the second PRINT should also give the above error,
     with the result being the integer 2030.

  o  A BASIC output routine, when run in BATCH, does not properly
     account for international characters (high-bit-on), which
     causes a variety of strange output, depending on how many such
     characters  are  being  printed.   For a short 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  The BASIC function DATE$() formats the year as only two
     digits.


INSTALLATION NOTES:

The system does not need to be rebooted after this kit is installed.
However, if the system is a member of a VMScluster, the other cluster
members should be rebooted or this kit should be installed on each 
system in order to make use of the new image(s).
