I can figure the parameter list part out OK, but what I was asking was whether the LE enclave needed by a C subroutine would be made available, and how. I'm *guessing* it might work by telling SORT it is "COBOL", but without actual experimenting I don't know. The FM is quite silent about anything except assembler and COBOL as MODS-type external exit routines to a JCL-invoked sort.
