How do you read Comp-3?

1. In case the COMP-3 Data, that you want to see is the data in a Mainframe File, and you would like to see the contents on TSO/ISPF, you can turn the HEX ON on the Command Line. In the below file, the last 2 Bytes are COMP-3 Data. You read the Hexa-decimal value in a top-down fashion.

How do I convert comp to numeric in COBOL?

RE: moving COMP value to numeric value

  1. 01 val1-display PIC 99.99999. Very Important! I am presuming that you have remembered to initialize. the val1 by coding :-
  2. MOVE 0.324 TO VAL1. So now, add.
  3. MOVE VAL1 TO VAL1-DISPLAY. DISPLAY ‘VAL1-DISPLAY=>’ VAL1-DISPLAY. Let us know how you go.

What is Comp 3 variable in mainframe?

COMP-3 is the equivalent of PACKED-DECIMAL. COMP-3 usage clause is applicable for numeric data type. If an item declared as COMP-3, the item appears in storage in packed decimal format. The right most half byte contains the sign value. COMP-3 data item contains any of the digits 0 through 9, a sign.

How many bytes S9 10 usage is COMP 3 will take?

An positive integer value which mathematically equal to +1. If you code an even number of digits, the compiler will always make it 1 byte larger internally. S9(7) COMP-3 will take 4 bytes of storage This is the preferred way as it is clear to anyone what was intended.

How do you convert packed decimals to numbers?

This document describes how packed decimal values (Computational-3) can be converted to numeric values via File Master using COBOL copybooks. The only method to get this done is to use a File Master Reformat data set, aka. REFFILE. (“11 REFORMAT Convert file from one record layout to another”).

Why do we use comp 3?

COMP-3 enables the computer to store two digits in each storage position, except for the rightmost position, which holds the sign. Suppose if you move 1234567 into a field defined 9(7). In DISPLAY mode, which is default, this field will use 7 storage positions.

Can we move packed decimal to numeric in COBOL?

Can we move numeric to comp in COBOL?

Any numeric variable (USAGE DISPLAY, COMP, COMP-1, COMP-2, COMP-3, COMP-4, or COMP-5) can be moved to a COMP-3 variable with only truncation and overflow issues possible, depending upon the PICTURE clauses involved.
