Data exception error in COBOL

[vlobo]

Hi ther,

I am experience a very strange problem in COBOL.

I have an variable defined as COMP-3 and all I want to do is ADD 1 to it. However, when I do this via the ADD statement I get a data exception error. I have tried a number of ways changing the 1 to +1, +001 etc, the Add to Compute etc. with no success.

The strange thing is that I have a similar variable defined in this same way on which I can perform the ADD with no issues at all.

Help would be greatly appreciated.

Thanks

Vanessa

Hello Vanessa and welcome to the forums,

You need to initialize your variable to zero before executing an add/compute to that variable. The literal being used is not the problem, the variable is the problem.

All variables (especially numeric variables) should be initialized.
