Scott, This is the Metal C "Programming Guide and Reference" (watch the wrap):
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/CCRUG130/CCONTENTS?SHELF=cbcbs1c0&DN=SA23-2225-03&DT=20100705233441 To answer your questions, No and No. AFAICT, Metal C is intended as an "HLL" (FSVO "H"LL) replacement for assembler, to be used for such things as exits or any other reason(s) you may have that require assembler-level capabilities. As the name suggests, it is a "bare metal" flavor of C, with a very limited number of C library functions available. All library functions are installed standard in z/OS system memory and accessed via "jump" control blocks. IOW, no LE here, and no actual library of functions so no "dynamic load" or "static link" of library routines, and if you write it on your system it should run on someone else's system at the same or higher (and sometimes lower) level. So no C library routines for threads or for TCPIP, but you could write your own in Metal C if you should choose to do so. I wouldn't, but maybe that's just me. OTOH you can write Metal C code that ATTACHes real z/OS tasks and WAIT's on real ECB lists (using the real assembler macros), or uses BSAM for playing with datasets, etc. There's more, but those are the "bare" facts as I know them.

I am particularly interested in what Metal C does not support. Does it support threads and TCPIP ?
