COBOL Interview Questions and Answers

 

Explain the difference between an internal and an external sort, the pros and cons, internal sort syntax etc?

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.
