Re: philosopy question: use LE & HLASM?

I'd say it depends which part of USS you are intending to use and if you are intending linking to anything else.
99% of the services can be straight assembler with no need for the aggravation of LE.
We use it for message queues, shared memory and sockets without any problems.
 

Just be careful if you decide you want mutexes (BPX1SMC). There's no stub so getting to the code is a pain...

Well, I would, but perhaps that's just me.

Calling the various UNIX System Services does not in
general require LE, but in an LE routine you also have
access to things such as: direct invocation of C
functions, callable LE services, and condition handlers.
