More curious than anything else.

Assembler programs do not need to be LE for calling BPX routines.
But one nice side effect of making an Assembler program LE-conforming
is that it can then call C functions directly (you do not need to
invoke a C program that then calls the C functions you're after).
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.


<I won't even put an ad here ;-) />

I hadn't even considered using C language subroutines.

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).
