Steve, AFAIK SPC and Metal C are all part of the same product. The SPC documentation is part of the XL C/C++ documentation as well, even though the Metal C docs are separate. The JCL EXEC statement to execute (whatever)C is all the same, EXEC PGM=CCNDRVR, and the STEPLIB's are also the same. The PARM controls what version you actually run. Tony, I'm not so sure about your statement that Metal C does not support "generate backlevel instructions". It seems to me that using PARM='ARCH(0),TUN(0)' would produce "backlevel" instructions from any of the C compiler outputs, would it not?
