Reply with quote

Hi,

How can I perform Numeric test for Comp variable?

Problem:

I have a variable declared as Comp. I want to know whether the value in the field is numeric. When I tested it using "IS Numeric", I received the following error message during compilation

IGYPA3256-S "WS-VARIABLE1 (BINARY INTEGER)" did not have a valid type for the specified class condition. The statement was discarded.

Please help me in resolving thie error?

You can't.
In a comp field, all values - from low-values to high-values - are numeric.

By definition, a computational item is a value used in arithmetic operations. It must be numeric. If a group item is described with a computational usage, the elementary items within the group have that usage -- so you can't escape (as Marso has said, you just can't.). It's programmers' responsibility to "move" correct data to fields with such definitions.

Suggest, you tell us what exactly you want to do. What you have posted may be just a way (you think) to achieve that; if you tell us what your final goal is, I believe, there can be alternate ways ...
