In my program one of variable definition I need to from 3 byte char to 3 byte decimal.
I changed x(3) to 9(3)v.
Is this is correct, how can I validate this decimal no.
If num_office is numeric
-------------
else
do something.

why 9(03)v here?
If there is a possiibility of getting non numeric char in your x(03) var, then simple move may give you incorrect results.
Try using function NUMVAL. |

Hi kiran/Abhijit,
Thanks for clarification.
Actually wt happened is, I want to get that value from DB2Table,it is defined as DECIMAL(3,0)(earlier it was CHAR 3) .According to this i need to change in my DB2-COBOL program.
It was validated using this
If num_office is numeric
-------------
else
do something.
----
Shall i use same for validation.
Abhijit-
All values are numbers only(length also 3 digits only).

DECIMAL(X,Y) datatype columns not allowed any other values other than numeric. So i think no need to check for whether the value contains numeric or not, as you are going to retrieve the value from DB2 table for the DECIMAL(X,Y) datatype column which always contains the numeric values. |

Maybe in the olden days, but the Fine Manual now states that the dataname can/must be "DISPLAY, NATIONAL, COMPUTATIONAL-3, or PACKED-DECIMAL when NUMERIC is specified".... |
