It should abend, you dont define REGION Parameter like that.
Check complete reference on REGION PARAMETER.

Q3How to execute a program if statement gets abbends?

Which statements. Statements in the COBOL Program don't get abended. If they fail such as S0C-7, job would abend with appropriate error- messages. And you'll have to restart the step itself.

Rgarding questions 4 and 5:
If you meant "how many FD statements can we have in a COBOL program" - the answer is 65,535.

I couldn't find a particular number for the maximum COBOL statements allowed, but you can calculate it yourself - statement by statement by reading the relevant chapter in the fine manual.

hi,

Virtual storage is the storage space that may be regarded as addressable main storage by the user of a computer system in which virtual addresses are mapped into real addresses.

Precisely, It is a operating system functionality to enable the user with more main memory than what is actually available physically.

This is acheived by Swappling in - swapping out of unwanted data from the main memory.


For your 7th Question:

As long as the mainframes server is on............your job will be remain in the system executing..
