IKJPARS has much more functionality than CLIST uses, e.g., it can syntax check the values.

CLIST has pretty much the same parsing capabilities as TSO. I think that's natural as both types of command processors were developed on the same platform. REXX OTOH was imported to MVS from elsewhere--VM? I miss those TSO/REXX capabilities. I once encountered a 'REXX preamble' that provided those parsing capabilities. Really complex code. I haven't seen it for years. Not sure I would line up today to adapt it for modern use. VM denizens don't even understand this conversation. . .

I have never used IKJPARS, so I don't claim to be an expert, and others might disagree. The issue I am struggling with is that for all of Rexx's parsing power, which is of course legendary, it does not seem well-suited to classic "MVS" (for want of a better term) quoted strings. I am considering an EXEC that would accept parameters of 'a quoted string', 'another quoted string', simpletoken1, simpletoken2, ... I don't see a good way to parse -- without resorting to a character-by-character loop -- input such as 'now isn''t the time', 'nor, is this', MYTOKEN, YOURTOKEN Am I missing something? It would be great if one could define the expected parameters and their format to Rexx in some systematic way, parse the user's input, and get back either parameter values in stem variables, or an error message to present to the user. Any suggestions?
