Hi,

What language zOS is written in to? Is it only Assembler or... I find that they talk about assembler but I'm not sure of.

a mix of assembler and PL/S PL/X ... PL/xxxxxx

the PL/xxxx family is a PL/1 like language with facilities to
let the user control register allocation and usage
inline inclusion of assembler fragments

if You run an AMBLIST on some system modules You will find out more
about the compiler being used

if You look at SYS1.MACLIB/SYS1.MODGEN
You will find quite a few BILINGUAL macros

the PL/X statements start with an * ( which is a comment for assembler )
the assembler part is surrounded by /* and */ which makes them a comment for th PL/X compiler
cheers

When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,
so that I am sure that the information requested can be reached with a very small effort 8-)
