Answer Posted / sreedhar naidu dhekodna
In the above Question there are no details about how the
file is getting created say, whether they are creating a
file using a program which may or may not populate data
into the file or using some IBM utilities for the sake of
only creation of file.
Consider the first Case: If file is getting created in a
step where the program may or maynot populate the file,
Then we can use IDCAMS or INSYNC or FILEAID or some
other utilities to check the emptiness of a file.
If it is the other case: Using file creation utilities only
for the sake of creation then only we can use cond
parameter.

A dd statement consists of 4 fields. Name them?
1) SORT FIELDS=(20,4,CH,D,10,3,CH,D) OUTREC FIELDS=(7:20,4,C' FUTURE ',20,2,10,3,1Z,1,9,13,7, 24,57,TRAN=LTOU,6X'FF') This example illustrates how a fixed-length input data set can be sorted and reformatted for output. The SORTIN LRECL is 80 bytes. The reformatted output records are fixed length with a record size of 103 bytes. SOLRF (the IBM-supplied default) is in effect, so unless the SORTOUT LRECL is specified or available, it will automatically be set to the reformatted record length of 103. in the above example i have some doubts that a) sort fields=(20,4,CH,D,10,3,CH,D) -what exactly it does and this fields related to output record fields or input record fields b)outrec used to refprmat the records after sorting that means could please reply me as soon as possible Thanks.

I want to JCL sort for Non-COMP and COMP-3 fields SORT FIELDS=(1,5,A,6,11,A,12,11,A,19,1,A,20,1,A),FORMAT=BI,EQUALS Length of comp bytes is 11 bytes which start at 6byte and 12 byte considering 11 bytes in comp-3 is 6 bytes. Can anyone tell if the above sort work SORT FIELDS=(1,5,A,6,6,A,12,6,A,19,1,A,20,1,A),FORMAT=BI,EQUALS does not works OK
