Re: COBOL Quest

[Bob Larkin <blarkin@xxxxxx>]

In addition to the answers from the others, there is one potential gotcha.
If RPG programs call COBOL programs, there can be a performance penalty. We
saw this in an RPG batch job, which called a COBOL progfram repeatedly.
Performance went from 10+ HOURS to <20 MINUTES, with one simple change. We
added a COBOL program as the first program. All it did was call the original
first program in the batch job, but it does some smoke & mirrors stuff, that
allows the ccalld from RPG to COBOL to be a LOT more efficient.
