The Question is:
We are running a command procedure periodically which does the following rename:
IF F$SEARCH("DISK$DISK0:[IAPROD.SIDATA.FINAID]PGDA03BK.*") .NES. "" THEN -
RENAME/LOG DISK$DISK0:[IAPROD.SIDATA.FINAID]PGDA03BK.* -
DISK$DISK0:[IAPROD.SIDATA.FINAID.ARC]PGDA03BK_PROCESSED.*
When there are multiple file types within the file, called PGDA03BK (ex.:
PGDA03BK.072 and PGDA03BK.073), files are renamed, but if there is only 1 file
(ex.:PGDA03BK.072) then the file does not get renamed.
Is the syntax of the rename command incorrect?.
Thank you,
William G. Kassar
The Answer is :
This appears to be expected behaviour.
Please follow the directions in the DCL manual for (re)establishing
the wildcard context for F$SEARCH -- the RENAME syntax used does
appear to be correct.
Whenever you issue an F$SEARCH containing a wild card, the search
context is retained until there are no more matching files -- until
a null string is returned -- or until a new F$SEARCH is started with
a different file specification.
If your command is executed multiple times, then the the second and
subsequent executions will use the existing F$SEARCH context, because
the file specifications are the same. This can give correct, but
misleading, results.
You should ensure any old F$SEARCH contexts are cleared before
starting a new search. For example:
$ Clear=F$SEARCH("")
$ IF F$SEARCH("DISK$DISK0:[IAPROD.SIDATA.FINAID]PGDA03BK.*") .NES. "" THEN -
RENAME/LOG DISK$DISK0:[IAPROD.SIDATA.FINAID]PGDA03BK.* -
DISK$DISK0:[IAPROD.SIDATA.FINAID.ARC]PGDA03BK_PROCESSED.*
Please check the log file for the command procedure for errors, as well.
If this is not the contextual processing within F$SEARCH, please contact
the support center, as details of the OpenVMS Alpha release and ECO level
will be required.
