I agree that SET variables are very useful. But I think that they could be more useful if they were more like UNIX environment variables - accessible to running programs. Perhaps via the ASASYMBM interface. The 100 char limit on PARM, limits how much data you can pass to a program using it. Another weird idea just occurred to me (though I may have read it here). A subsystem, written by IBM, which "emulates" a sequential file. But what is read are the subsystem parameters on the JCL. Each subparameter would be a separate record when read by the program. This could be used to replace small SYSIN-like data with data which includes symbol substitution. Eg: //DEL EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //SYSIN DD SUBSYS=(READ, // ' DEL &DSN', // ' SET MAXCC=0'), // DCB=(RECFM=FB,LRECL=80,BLKSISE=80) -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
