Worked for Burroughs for 38 years.
Languages I used::::
SOAPII
AUTOCODER
GMAP
COBOL
B3500 Assembler
SDL
ALGOL
SDL was the best. Developed by Unisys small systems for system programming. System Development Language.
The reason I chose IBM was other firms had programming ads all over the place in the NYT, all using IBM software. So if I wasn’t offered an employment opportunity there, I had many other firms to apply to.
