Move all the records to array table.
then compare with each other,then swap that two records.
like IF ARRAY(I) > ARRAY(J)
MOVE I TO WS-DATA
MOVE J TO I
MOVE WS-DATA TO J
ELSE
COMPUT I = I + 1
PERFOEM SAME PARA UPTO FS = 10

In Cobol, Why we have to give one blank space between program-id and program name?

PK.Ganapathy

• Jan 7th, 2015

That is the syntax of the language. Why do we begin English sentences with a capital letter?

That is how we are taught.

In the same way, you need a space.

Based on which scenario , we can prefer static or dynamic call for our program?

PK.Ganapathy

• Jan 7th, 2015

Some of it depends on shop standard. The shops I have worked on prefer keeping subroutines as dynamic. This keeps the region usage low and loading modules to memory as needed. Static increases load module size.

Mangesh K

• Jun 20th, 2012

There are various scenarios based on which we can go for either static or dynamic:
1. When module is big then (i.e. module contains lot of lines) static is better.
2. Simplicity is achieved via static call
3. Dynamic call is prefer when module size is less and modules being frequently compiled

How to find a program whether it is a COBOL or COBOL-DB2 program by looking at JCL?

PK.Ganapathy

• Jan 7th, 2015

Pure COBOL programs can be executed by EXEC PGM=. DB2 programs will need to be executed by EXEC PGM=IKJEFT01 with the SYSTSIN DD card with the plan/program name. If you are using IMS for checkpointing, then it is a little tricky.
