The SelfChk Unit - Turbo Pascal Revision History. v1.1 - 2/05/90 ~~~~~~~~~~~~~~ Fix in... Documentation : Compiles under versions 4.0 and above, not just 5.0/5.5. SCHKINST : Would not install CRC data (wrong data location) in programs of any significant size (Yikes!). Due to the way TP handles multiplication of LongInts with other constants. Don't ask me why, but TP returns a regular Integer result, dropping the upper byte pair of the LongInt which didn't help us any. Resolved w/ an addition loop. SelfChk.Pas : Added 'exec_fname' variable initialized at runtime to the full drive/path/filename of the executable. v1.0 - 1/22/90 ~~~~~~~~~~~~~~ Initial Release. Mike Durkin
