For example do I define the ALIAS and then perform the MERGECAT? or I perform the MERGECAT and then define the ALIAS?I don't have a test system in which I can try it out. Below is my jcl to run the MERGECAT:/* //STEP1 EXEC PGM=IDCAMS,REGION=2048K,TIME=1440 //DD1 DD VOL=SER=MCAT03,UNIT=SYSALLDA,DISP=OLD// DD VOL=SER=TST001,UNIT=SYSALLDA,DISP=OLD//SYSPRINT DD SYSOUT=* //SYSIN DD * REPRO - INDATASET(TSUT3.MCAT) - OUTDATASET(USERCAT.APPLIC) - LEVEL(CTPRT17) - MERGECAT - FILE(DD1) /* // Thanks. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
