not sure if this is a very basic question..but suppose i have a variable VAR1 defined as X(12) which extracts data from the table stored as a number value 9(8)V9(4). So in my program can i use the following
| Code: | 01 WS-CAST-AS-NUMBER.
10 WS-NUMBER-X PIC X(8).
10 WS-NUMBER REDEFINES WS-NUMBER-X PIC 9(8).
10 WS-DOT PIC X(01).
10 WS-DEC-X PIC X(04).
10 WS-DEC REDEFINES WS-DEC-X PIC 9(04). |
| Code: | | MOVE VAR1 TO WS-CAST-AS-NUMBER |
So WS-NUMBER have the whole number part and WS-DEC have the decimal part correctly?
Will this work..

Its working.. because all values in the table are having 8 whole numbers/4 decimal numbers and i'm not authorised to edit a value in the table. but i just wanted to confirm if it would work for others as well... such as when it is 123.44 i would want WS-NUMBER to have 123 and WS-DEC to have 44

Does the table store explicit decimal point? You are retrieving 12 bytes but if it has an explicit decimal point, the length is 13 (8+1+4). Also you are retrieving the table data into a character field it is left justified.
what happens if your your input is
| Code: |
1.1234
12.1234
123.1234
1234.1234
12345.1234
123456.1234
1234567.1234
|
Does your redefine work for it?

If VAR-1 is defined as a DB2 data type DECIMAL (12,4), then you need to MOVE VAR-1 TO WS-NUMBER where | Code: | 01.
05 WS-NUMBER PIC S9(8)V9(4).
05 redefines WS-NUMBER.
10 WS-NUMBER-INTEGER PIC 9(8).
10 WS-NUMBER-DECIMAL PIC S9(4). |
You need to study the PICTURE and USAGE clauses and MOVE statements in the Language Reference manual.
