How do you handle empty files in a JCL ?

Answer / guest
Yes, we can handle empty file in JCL, there is utility
provided by IBM "UT939" ,eg //STEP1 EXEC PGM=UT939,
IF step1 return code is 4 then there is empty file and else
if return code is 0 (for non-empty file). We can handle
this with COND parameters whether to execute next step or
not if file is empty.
SUPPOSE WE DON'T WANT TO EXECUTE THEN
eg //STEP2 EXEC PGM=XXX,
COND=(4,EQ,STEP1)

Read first record of the file using IDCAMS, It will return
the cc=0 if the file is not empty, otherwise it returns
CC=4.

If a field is declared as a comp-3 field and if we want to sort a dataset based on this field, then how will the sort card be??? e.g- if we want to sort by a field which is defined as a PIC X(5) then we will mention - sort fields=(1,5,ch,a). Likewise if a field is defined as PIC S9(10)COMP-3 then in this case how will the sort field be defined (because in this case a sign is also involved)???
