How can I delete disk files based on names in another file?

IEFBR14 does not accept any "input" data.  It is a "dummy" program that clears the value in register 15 and then branches back to the "caller", which is the z/OS.

You could use IDCAMS using the IDCAMS delete command.  So in your file you would have lines like:

DELETE  GO1.OSCR.D1UNL.GO1DDEV1.GO1SCAM1.PUNCH

Then your JCL would be something like

//S01OF99 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD DSN=DSN=GO1.OGADM31.ATEMPFIL,DISP=SHR

Now, you could also use IEFBR14, but you would need a unique DD statement for each file that would look something like:

//FILE0001 DD DSN=GO1.OSCR.D1UNL.GO1DDEV1.GO1SCAM1.PUNCH,DISP=(MOD,DELETE)

You need to use "MOD,DELETE" instead of "OLD,DELETE."  If you use OLD and one of the files in the list did not exist, then you would get a JCL error.  With "MOD,DELETE" if a file does not exist, the system will create it and then delete it right away.

If the files you are deleting are not SMS managed, then you would also need to add space and volume parameters in case the files don't exist.
