My challenge is that I want my output file's length to be determined at run time (390 Cobol). I want it to be fixed (not variable), but potentially a different fixed length each time it runs. This length could EITHER be taken from the JCL DD statement (new allocated file, complete with DCB information) or calculated in the program -- either approach works for me, although the latter is preferred. From all my reading, it appears that to use the information from the JCL, I *should* be able to code the output file FD with "RECORD CONTAINS 0 CHARACTERS". However, the Cobol compiler gives an error on the OPEN OUTPUT for this FD:
IGYPA3143-E Physical "SEQUENITAL" file "OUT-FILE" specified in an "OPEN OUTPUT" or "OPEN EXTEND" statement was defined with a "RECORD CONTAINS 0 CHARACTERS" clause. The statement was processed as written.
This works fine for the input files, by the way, but I can't figure out how to do so for the output file.
