COBOL Interview Questions and Answers

 

Explain how will you differentiate 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.
