What is the reference modification
ramesh4greek

Yes the above 2 steps are correct. By using reference modifcation we can write reverse of a string, right angle and piramid.........

Reference modification is used to retrieve/replace the set of characters from a string.Ex: MOVE WS-VAR(1:5) TO PV-VAR. MOVE 'GEEK' TO WS-VAR(1:4).

Comp and Comp-3
In real time in which situations we can use comp-3 and comp. What is the major difference between these two?
ramesh4greek
- Jun 11th, 2010
In COMP the data is stored in binary format, and displayed in character format.In COMP3, the data is stored as the above formula. For lower bound values COMP is best and for upper bound values COMP3 is better.

Comp-3 is more efficient than Comp.Comp: Binary representation of data, can contain only S, 91 - 4 : 2 bytes (1/2 word)5 - 9 : 4 bytes (Full word)10 -18 : DoublewordComp-3 : P...

If the main module is calling submodule statically then the sub module's code will be copied into the main module in the comiled version but this wont happens in DYNAMIC calls case.Hope it will help.Regards,Ambadi. Ramesh.

What is the difference between a subscript and an index in a table definition?
A subscript is a working storage data definition item, typically a PIC (999) where a value must be moved to the subscript and then incremented or decremented by ADD TO and SUBTRACT FROM statements. An index is a register item that exists outside the program's working storage. You SET an index to a value and SET it UP BY value and DOWN BY value.

An Index is the value of OFFSET or DISPLACEMENT from the starting of the array. The index is defined as part of the occurs clause in the definition of the array as shown below. 01 WS-TABLE-ARRAY. 0...

SUBSCRIPT: No. of occurences is called Subscript.INDEX: The disposition of the element.Index can be used in Table data searching and Sorting but Subscript won't be useful for the above.

77 WS-AMT PIC ZZZ999.ADD 100 TO WS-AMT WILL RESULT INa) COMPILATION ERRORb) SOC7 ERRORC) NO ERROR
kkreddy98
- Sep 5th, 2007
It will give compilation error because WS-AMT is a edit-item and edited items can not be used in arthmetic operations.Thanks,Kotireddy k
kavitha
- Sep 25th, 2006
It will not show any error. Becos "value" clause is not needed for this variable to show compilation error and the ADD syntax can be used to add value to alphanumeric variable. Alphanumeric variable can handle numeric values (ex. 10, 20) but vice versa cannot happen.
