Actually, continuation is simple. I defined YY_INPUT so that it reads all the physical lines in a logical JCL statement and presents "pure" JCL (the "logical" JCL statement, so to speak) to its caller. No continuations, no JCL comments, etc. Makes parsing much easier. At present, I'm stuck in that I am too ignorant. I have many shift/reduce errors, likely because my Bison input is not properly formed. But work just picked up, so this is once again "on the shelf" until I have some time. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
