Compute:
PROC[
srcCreate: LONG CARDINAL,
switches: CompilerOps.LetterSwitches, compilerVersion: TimeStamp.Stamp,
directoryEnumerator: PROC[PROC[TimeStamp.Stamp]]]
RETURNS[bcdVers: TimeStamp.Stamp];
for computing a version stamp
the directoryStamps are in the order of the DIRECTORY clause
stamps for the hidden directory entries are not included
precise switches must be specified (except /d, /g, /p are ignored)
