There are probably several items on cbttape.org that may already do some of what you are looking to do.
What problem are you trying to solve? Would it be better to use something already created or are you looking to understand some function better? REXX has some built-ins, SAS has some functions, ISPF Services, and so forth. Could you provide more details on what is driving this question? There might be better solutions.
