AREV Specific

I have a program which uses the PCPERFORM statement to rename a DOS file.

Ie.

SUBROUTINE RENAME(OLD_FILENAME, NEW_FILENAME)
DECLARE FUNCTION UNASSIGNED
IF UNASSIGNED(OLD_FILENAME) OR UNASSIGNED(NEW_FILENAME) THEN RETURN
CMD=REN ":OLD_FILENAME:" ":NEW_FILENAME
PCPERFORM CMD
RETURN

This works most of the time. But occasionally (about 1 in 100 times) the program will break on the PCPERFORM line, saying that a runtime error was encountered. But it doesn't say what the runtime error is.

I'm using AREV 2.03

Any advice/ suggestions?

We'd guess you don't have enough memory - try SUSPENDing instead.

It runs much much slower than using PCPERFORM.

Does PCPERFORM lose a bit of memory each time it is run?

Would a FLUSH or GARBAGECOLLECT do anything?

Well yes, SUSPEND rolls memory out to disk thus ensuring that you have more RAM available to perform the operations you want to. PCPERFORM just loads another command processor into the RAM that is left. RAM is not static and the amount available will depend on what variables are in use. A garbagecollect and flush may help.
