Does REVIEW work on MVT?
No, but a porting of some functions would be possible. The &MVS switch should be set to 0 for pre-MVS TSO systems (which means MVT and SVS). The source would probably have to be reassembled on an OS/390 system and link edited with ‘DC’, and the load module copied to the MVT system. Recent (ie. since 1984) additions to REVIEW code have not always employed the switch at all places where conditional assembly should take place, so be prepared for some problems. REVIEW might just now use too much storage to run under MVT, but this will of course depend on the TSO REGION size. Logic paths using the “new” GETMAIN/FREEMAIN SVC (SVC 120) may cause additional problems. There may also be the question of TCAM vs. VTAM support to be considered. REVIEW also uses several TSO/VTAM terminal control macros which issue SVC 94. Speaking of MVT, the REVCAT program may be of interest to assist with the administration of OS catalogs (aka SYSCTLG data sets or CVOLs).
