Any dynamic STEPLIB functionality introduces potential System Integrity exposures, because some parts (modules) of a program may have been loaded from one library and others from a different, incompatible library. As IBM takes the System Integrity of z/OS very seriously, it is very unlikely that IBM will officially support that function, in my opinion as a former z/OS developer. z/OS provides tasklibs, and some functions within TSO/E and ISPF to manage dynamic tasklibs, which do not introduce such exposures. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
