I would guess that by "fixed file" the OP means "a hard-coded DSN as opposed to a system temp DSN."
Can one allocate two DD's to the same temp dataset? Would the following work? (Untested) //DD1 DD DISP=NEW,DSN=&FOO //DD2 DD DDNAME=DD1 I have never done that. I have only used DDNAME= in the situation where I wrote to that DD rather than the referred-to DD name.
