I only used 3540 on a DOS/VSE system. They could be referenced on ASSGN statements // ASSGN SYSxxx,3540, and DLBL identified which fileid on the diskette. http://bitsavers.trailing-edge.com/pdf/ibm/370/DOS_VSE/SY33-8571-7_DOS_VSE_Handbook_Feb79.pdf MVS input support was only for instream input datasets like: IBM 3540 diskette volumes can contain associated data sets. Associated data setsare treated like in-stream data sets and are spooled in as SYSIN data sets. Theseassociated data sets are identified by coding a DSID parameter and, optionally, avolume serial on a DD * or DD DATA statement in the input stream: //ddname DD *,DSID=xxxx,VOLUME=SER=yyyyyy MVS output for sysout: Data sets are written on 3540 diskette volumes by coding: //ddname DD SYSOUT=(class,diskette-writer),DSID=id //ddname DD SYSOUT=(class,diskette-writer),DSID=(id,V) Dana ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
