Yes. I personally use memset all the time. But this is not the point.
We have hundreds of programs in production that use this kind of
initialization.
And we don't want to check and change them all. If the IBM people are
wrong in
their interpretation of the C language definition, they should fix their
compiler,
and we would simply recompile all our programs without having to examine
them and to lookup all such declarations and initializations, which can
be costly,
given some 2000 programs and 7 millions lines of source code.
Unfortunately, I myself have only written some dozens of these 2000 C
programs :-)
(and many of these have gone through other hands through the past 15
years).
Kind regards

Sorry for the missing line feeds.

C statement:
* scp1215aus out1215 = { 0 };

Kind regards

Just me (and I'm not really good with C), but why not just use memset()?
memset(&in1215,0,sizeof in1215);
