The Question is:
Can you please let me know if is is due to the different version of OpenVMS V7.2?
p.s. I have been working in VMS/OpenVMS since 1980 here in Montreal
The Answer is :
Use the SET FILE/END_OF_FILE command to relocate the end of file (EOF)
marker to the end of the allocated storage -- the OpenVMS Wizard has
never seen a (well-behaved) application read a file past the EOF.
Given that the file is locked, it would appear that whatever has
been writing to the file has not finished writing and it would
appear that the requested access to the file is incompatible with
the shared access allowed by the writer (if any).
For details on sharing file access, please see the OpenVMS FAQ.
If this file is a log file for a batch job, the queue manager
normally creates the log file for shared write, though it is
possible control the frequently of updates (writes) to the log
file using a SET command.
