What is the relation if any between RDR MODULE on LISTSERV 191 and the RDR MODULE on MAINT 190 (S-disk)? I ask because CMS RECEIVE fails to work if I have LISTSERV 191 accessed. RECEIVE calls RDR, picks up the LISTSERV version, which results in a message to the effect Invalid parameter MSGSUBS -- RECEIVE EXEC S line 214 Examining RECEIVE EXEC, I find lines 211-214 to read * VM32507 changed the following line to add MSGSUBS. RDR (LIFO MSGSUBS &AIG = &CONCAT OF RDR &RC &IF &RC ^= 23 &GOTO -&AIG
