I have to tell you that I tend to ignore what you say when you start arguing religion. 
 You didn't even give a hint as to why you think PL/X is better than C.

Some z/OS comp;onents are still written in the language of IBM's HLASM, but
much of it is written in PL/X, which is also a PL/I dialect but which unlike
PL/S does a great deal of optimizing before it emits assembly language.

Many of you will find this view uncongenial, but PL/X is in fact a much
better language for systems- software implementation than C or,
particularly, C++.

IBM has never released mainframe PL/X for others to use;  this policy is,
however, under review;  its syntax is no longer 'secret' (There will in fact
be a SHARE session on it next week); and it may in the fairly near future be
licensable.

Even so, it is unlikely to be a useful implementation vehicle for generic
Linux components because the likelihood of non-IBM implementations of it is
negligible.
