Gene, I thought any MI built-in can be called, even if not wrapped by IBM into a C api, but I can't find that one in any of the system header files. Usually linkage pragma is used, i.e.: #pragma linkage( _CLRBTS, builtin ) followed by the function prototype definition, i.e.: void _CLRBTS ( void *, unsigned ); Same doesn't work for ADDLC so I can only guess it's not made available by IBM as bindable C interface. What exactly does ADDLC do? (sorry, I don't code in MI yet but maybe when I get some free time...)
From what I gathered it concatenates two character strings, right?
If I interpreted correctly, strcpy followed by strcat would work on null terminated strings, or 2 memcpy-s for non-null terminated string. I probably interpreted ADDLC description wrong. Sorry for raising more questions than answering...
