I actually picked up an old book on os/360 assembler at a library sale some years ago. Back in those days assembler was the what applications were coded in. Some of the airlines had their reservation systems in it until fairly recently. It’s not bad so far as assemblers go.
- jsymolon 5y agoIt's not assembler that'll get ya, it's the JCL. Past Technical Lead, "Don't bother w/ creating the JCL, copy it from <this job>"
- pinewurst 5y agoAirline reservation systems didn’t use JCL (something from OS, MVS, etc). They used a special transactional OS called ACP/TPF instead.
- euroderf 5y agoBad memories of JCL. An IBM mainframe at college, late 70s, and only a few guys that hung around the keypunch room knew the secret incantations. SYSIN DD *
