I'd like to hear other opinions about this comparison of C/C++ and HLAsm. The
comparison revealed some interesting insights between C/C++ and HLAsm but was
not as helpful as I wished because the products solved very different problems.
There is a lot of motivated reasoning used when discussing
I forgot to mention that in my case C++ would have forced me into difficult
design choices for automation. While events rarely change on z/OS, the
possibility still exists. C++ can extract attributes (fields) during runtime
which I can use to dynamically build each event type but I risk
Thanks Chris for answering so many questions. I should have read part 2 before
answering part 1.

I'm really surprised that yours is so much less than my 80,000 lines (asm &
macros). 2.5X is very significant.

Very true Peter. Very bad choice of example. In C, we have reference /
dereference which

Hi Chris,
I can simplify this with 3 simple questions. Realize I'm very pro-C/C++ with a
couple of caveats. I would have preferred C++ for my product if it didn't
create more problems than it solved. I'm curious about your experience as a new
convert to C++. Unlike any other applications, z/OS

I'd guess that this is not a good way of doing this, if it means that this
address will be used as a base register, since that is both unnecessary and
(worse) results
