hi Peter,

The XL V2.4.1 compiler is for the Unix Services Shell environments only. The XL 
V2.4.1 compiler can run on z/OS V2.4 or z/OS V2.5. It is a compiler designed to 
help port applications over to z/OS from other platforms.
For C (or C++) developers in a JCL only environment, they can continue to use 
the XL V2.4 compiler.


Hope this helps.  Thanks.
