Hello maridawson,

What do u mean by renaming data item ?
Can you provide an example?

suppose if i rename a data item like in the following ex:

01 ws00-input.
05 ws-in1.
10 ws-in11 pic x(2).
10 ws-in12 pic x(2).
05 ws-in2.
10 ws-in21 pic x(2).
10 ws-in22 pic x(2).
05 ws-in3 pic x(1).
66 ws-ren renames ws-in12 thru ws-in22.

now can i use ws-ren in arithmetic operations like add,sub,multiply,divide?

if you try it will give error
Code: Receiving operand "WS-REN (GROUP)" of an arithmetic statement was neither
numeric nor numeric-edited.

maxcc 12

are you sure the fields are alphanumeric??

66 items are one of those cobol things that 'is suggested not to use'. It is only slightly less dangerous than MOVE CORR.

Look at your compile listing and you will see that:
1) RENAMES creates a Group item with an ALPHANUMERIC attribute.

2) The length will be equal to that of all the elementary items referenced in the RENAMES clause.

The basic use of RENAMES is to allow MOVEs of elementary items as a group.

As Sambhaji showed, not applicable for arithmetic functions.

can we use renamed elementary data item for arithmetic operations ?

According to the manual, a renamed elementary numeric item remains a numeric item and hence could be used for arithmetic operations. Renamed group items are alphanumeric, however.
