Jeff,

What is the significance of the semi-colon. Consider:

: PURGE ABC;TEMP
                                 ^
File "ABC.HGLB.Y2KOLD" not found.  No purge done. (CIWARN 383)
: PURGE ABC,TEMP
                                 ^
File "ABC.HGLB.Y2KOLD" not found.  No purge done. (CIWARN 383)

There was a time when MPE[/iX] would issue a scolding message "expecting
comma" when a semi-colon was used, but executed the purge command. Now
either punctuation mark is accepted.

Less elegant:

  PURGE !file ;temp >$null
  PURGE !file       >$null
  ERRCLEAR

If the file doesn't exist you get a warning (sent to $null) so there
is no need for a CONTINUE.
