While I agree, I also disagree. There is really a big balancing act that IBM is always on and I can feel sympathy for them (to a certain extent). I would suggest that to implement something in this area to provide backward compatibility IBM could leave it at 100 AND create a new option called (something else) like longparm and allow over a 100 characters and then instead of a half word do 8 byte length and provide 16G of storage. But that has issues as well. But I would suggest to you that you put in a SHARE requirement for this and let IBM respond to it and then complain if they don't come up with a way to pass more than 100 characters. If there is already a requirement revote on it and resubmit it and see if you can't get IBM's attention on it (again). I would also suggest that IBM *KNOWS* about the issue and either they are at odds on how to implement it or don't want to implement it or otherwise it would have been a new function or facility in a 64 bit OS. In any case submit a requirement or revote one that has been submitted.

I'd be overjoyed if IBM would admit to the possibility of a parm string up to 32,767 bytes, and design parm-driven software with that in mind. And allow JCL to accept a parm of that length. Changes to code would be minimal, since it already uses a halfword length. Changes to JCL processing might be rather major, so I don't expect this to be done overnight, as long as it's kep in mind.
