Hello Mr. Kiran V. Sutar,

For the program that catches what you thought you did
with what you actually did, The D51.EXE disassembler is
great for finding errors that Oleg caught.

I took your coded compiled it with ASEM.EXE and ran
D51.EXE disassembler on it and it allowed for the errors
to be shown easily.

D51.EXE disassembly is public domain software and is
easy to run.

Regards,

Charles Bannister
