I write my DB2 stored procedures and user defined functions in assembler, and they are required to be LE compliant.

Fw: Language Enviroment HLASM question.
If you think that using any of the LE callable services might be useful (now or in the future) for the program, that would be another reason.

Re: Language Enviroment HLASM question.

What about if it uses the BPX... subroutines to do UNIX work? Having a runtime that provides a bunch of services and callable library functionality is a somewhat alien concept to most assembler programmers. I am no fan of LE, but in the absence of anything better it is the best tool you have. High level language programmers take their standard library routines and runtime support for granted and there is no reason assembler programmers cannot benefit as well. Once you have leveraged those capabilities it can be quite painful going back to a true bare-metal environment. If you're just doing the moral equivalent of a single load module main() program in assembler, then there is nothing to be gained or lost. However, if you're going to call other programs (even within the same lmod) and/or you want to leverage runtime capabilities or callable library routines, then there really isn't any better way.

So printf, scanf, and so on can be invoked directly from the Assembler program. But you don't want the tail wagging the dog, it's always important to clearly define what the program is to be doing.

Re: Language Enviroment HLASM question.
I do have one thing that I don't like. My diagnostic abends result in LE getting control and messing around with the environment. It is weird to see a U4087 on my job when I __know__ that I caused an S0C1. I wish that I knew how to perculate the original abend code up to the JCL level. Everything seems to come out as a U4087 (S0C1, S0C3, S0C7, etc). Arguably that's what condition handlers are for. You would want to get control and belch up some more coherent diagnostic information - hopefully even some messages in the job log. That's (in general) much more useful than the usual symptom dump and abend code.
