Hi,

If we declare the curosr in procedure division and if we declare it in WS Section, wil lthat make any difference in the two? If yes, what are the differneces.

There is no difference in the two as far as the definition of the CURSOR is concerned. If you declare the CUROSR in PROCEDURE DIVISION, the OPEN should logically be done after the DECLARE.

Thanks Anuj. I knew that there is no difference but was not sure about the OPEN statement. Thanks for the clarification.

For instance, consider CURSOR as a variable which you'll use in your program. In most of the languages, you can use the variable in the logic of the program later, only if it is declared somewhere before it is used. Same is the case with CURSOR, unless system has its definition, it won't recognize it.

You do not find such definitions in book. Thank you!
