This doesn't really sound like a philosophy question, it sounds like a need question. Do you need anything that LE can provide (be that functions or the stack or something else, even something that just makes it easier to code what you need to code)? If the answer is "yes" (or perhaps even "maybe" to help with future changes), then you should use LE. If not, then why would you? The LE stack is of course faster for an individual obtain than getmain but if all you need is one getmain, then the LE setup that would enable you to use that stack would be far more costly.
>Gripe time: Dear IBM LE, please allow use of RSECT in CEESTART. Perhaps I'm missing the benefit. RSECT is ignored within z/OS processing except for modules in IEANUCxx. So is there some assembler benefit over and above what RENT checking gets you? Wouldn't *PROCESS RENT xxxxxxxx CSECT (or having RENT in your assembler invocation parameters) basically be equivalent to xxxxxxxx RSECT Peter Relson z/OS Core Technology Design
