ECO KIT SUMMARY:
An ECO kit exists for DEC$BASRTL.EXE OpenVMS Alpha V7.1 through
V7.1-1H2. This kit addresses the following problems:
Problems Addressed in ALPBASR02_071
o Under DEC BASIC with DEC$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.
Problems Addressed in ALPBASR01_071
o A BASIC program may ACCVIO or hang in an infinite loop in
DEC$BASRTL if AST calls a BASIC routine.

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).
