Re: COBOL TEST-3 WITH ANSWERS

Postby Robert Sample » Wed Dec 08, 2010 5:46 pm

1. Your answer disagrees with section 5.3.15 of the COBOL Language Reference manual:
If the SEPARATE CHARACTER phrase is specified, then:

* The operational sign is presumed to be the LEADING or TRAILING character position, whichever is specified, of the elementary numeric data item. This character position is not a digit position.

* The character S in the PICTURE character string is counted in determining the size of the data item (in terms of standard data format characters).


3. Check section 6.2.26 of the COBOL Language Reference manual to see why your answer is wrong.

7. Considering the default is WITH TEST BEFORE, would you care to change your answer?

8. Your answer is wrong -- EVALUATE doesn't work that way; see the COBOL Language Reference manual for details.

14. Considering the MOVE ZERO TO GROUP-ITEM will NOT take into account the USAGE COMP variables, would you like to change your answer?
