I have a DCL script on VMS which calls a perl script. Is there a VMS/DCL command I can use that will tell me every file handle opened by the perl script?
Set default to the disk the app runs from (or you might have to try each disk in succession if it's a really large or distributed app). Then the command is
show device/files/nosystem
If you're on a more recent version of VMS and the lists are too long, you can pipe it with a search by doing this:
pipe show device/files/nosystem | search sys$input (name of perl script)
