What is the logical difference between Move A TO B and COMPUTE B = A?
prasenjit_in

Move replaces values one by one, depending on the data type move is from left-right/right-left.Compute on the other hand completely deletes the previous value in the variable and writes the new value to.

What is an in line PERFORM? When would you use it? Anything else to say about it?
The PERFORM and END-PERFORM statements bracket all COBOL II statements between them. The COBOL equivalent is to PERFORM or PERFORM THRU a paragraph. In line PERFORMs work as long as there are no internal GO TOs, not even to an exit. The in line PERFORM for readability should not exceed a page length - often it will reference other PERFORM paragraphs.

A RETURN_CODE shows the status of each step within a job and the maximum RETURN_CODE is 256, where as MAXCC shows the end of the programme status, if the MAXCC is ZERO it means that job is executed successfully. We have MAXCC are like 0,2,4,8. MAXCC=8 means fatal error.

Answered by: Gayathri
- Sep 4th, 2005
COMP Usage is used for data items of numeric type. There are 4 types of COMP usage.
1.COMP : Used only for integers.Either half word or full word .
2.COMP -1 :Used for floating points.Internal representation is hexa decimal.full word is used.No PIC Clause .
3.COMP -2 : Similar to COMP-1.Only difference is double word(8 bytes )is used
4.COMP -3 :Interenal representation is decimal.Each character is assinged to half byte.The sign bit is assinged to right most bit. The no.of bytes required for n characters is (n/2) + 1 (rounding down)akhileshrewa

The answer is dif we ignore the spelling mistakesnow perform pri-out until sw=1; while reading the in-file its automatically adding one to the subscript.so the new value of sw=1 and then the loop stops.i think the prob is with the logic
