Hi all,

I got a small doubt. Please clarify me

What is the advantage of Internal SORT (COBOL) over the External SORT (JCL) ?


Thanks in advance.

Hi praneeth,
An external sort is not COBOL; it is performed through JCL and PGM=SORT. It is understandable without any code reference.
An internal sort can use two different syntax?s:
1) USING, GIVING sorts are comparable to external sorts with no extra file processing;
2) INPUT PROCEDURE, OUTPUT PROCEDURE sorts allow for data manipulation before and/or after the sort

Hi,
Simple sort(USING,GIVING) is comparable to external sort. Complex sort (INPUT/OUTPUT PROCEDURE) is comparable to external sort (by using INCLUDE,OMIT,INREC,OUTREC and others). External sort is faster and advantageous.I don't find internal sort advantageous in any way compared to external sort. Experts,help!
Thanks,
Sridevi.
