The classic remedy in situations of the sort Arthur Fichtl describes is to write a macro, here one called MVCIN, that performs the operation not supported on some target machines.
The HLASM will---and its immediate predecessors would---use a machine instruction I known to it for a particular assembly and, failing that, expand a macro named I known to it instead. The distinction between assembly machine and execution machine---what COBOL used to call source and target machines---is of course crucial here, and in some environments it is difficult to make [or preserve administratively] . --jg ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
