DELFIL is a program which deletes files. Its function is mainly to delete files which PIP can't - files with rib errors. The command string is of the form: *DEV:FILE.EXT[PROJ,PROG,SFD1,....]/SWITCH where "DEV:" is DSK: or some file-structure name, "FILE.EXT" is a particular file name, a UFD name, or omitted Switches include: /C - Delete all empty UFDs (of PPNs which aren't logged in) from device DEV (FILE.EXT is ignored) /D - Delete the named file (tries to delete with regular RENAME, if that fails, it uses SUPER USETO) /S - Delete with SUPER USETO, even if no RIB error exists /R - Delete all (and only) those files from the named UFD which have RIB errors NOTE that the disk space for a file is not returned if a file is deleted with SUPER USETO until the disk is refreshed.
