Oh what a tangled web to weave. ( Yes, I've read the book ).

We had a discussion on changes we would like to see in JCL. Well, I am wondering if perhaps what should be embraced in a variation of Knuth's "Literate Programming" in which the program source is actually embedded in the documentation. I am wondering if some JCL documentation company might consider this to be something as a possibility for a product. This would combine and centralize the maintenance of the JCL with the documentation for the job. Combining this with the DCF thread, how about something like DCF's GML which could be run through some program. One DD would output the JCL, such as could be sent to the internal reader. Another DD would contain formatted text, such as AFP or PDF output. Might even be nice if this vendor program could be written so that a scheduler program, such as CA-7, could use it as a "preprocessor" for jobs that it submits. This would be so that the CA-7 JCL library would contain the "Literate JCL" and be able to "directly" submit it. Of course, said vendor product should also be able to do a JCL syntax scan to detect syntactic JCL errors. Just a wacked out thought for the new year. ref: http://en.wikipedia.org/wiki/Literate_programming
