>I used records in a certain table to check who's using the application. Now I use dummy files for that purpose. When checking I first TRY to DELETE the lockfile. If the file still exists afterwards, then the user is still using the application. DELETE is quite fast, but I'm wondering whether there's another even faster way to check it.

Not sure if this is faster:

lnHandle = FOPEN(full_path,12)
IF lnHandle < 0
   *** Somebody use the file
ELSE
   FCLOSE(lnHandle)
ENDIF
