IBM Mainframe COBOL vs. AS/400 COBOL
I've been transferred from the mainframe to an AS/400 team, and was
wondering if there were any significant differences between the
IBM mainframe COBOL and the AS/400 COBOL. So far they seem virtually
identical (other than COMP is COMP-3, you gotta say BINARY.)
By the way, are there any differences in coding to get better
performance? In the mainframe, I made my subscripts COMP SYNC (I don't
like INDEX fields).
