Easytrieve positive/neg numeric values

Hi,
I read a file with 2 values, both numeric length 6, both will always be positive, but are not signed.

I want to subtract the second value from the first and display the result, if the result is negative, I need to show the Neg Sign.

I am having trouble showing the sign on the result, any suggestions?

I tried a mask, with no success. I am thinking I need to sign the values I read but dont know how this is done

Any help much appreciated

Hello,

Without studying the code, here is one way:

Define a signed field and compute this field as the subtraction of the 2 values. Then move this signed value to your output field definition.

IIRC, if you define your fields with decimal places e.g. "6 N 0"
Easytrev considers such fields as signed.

hi, if you want to define a signed variable, try this
ws-avariable-1 w 6 n 0 // signed
ws-avariable-2 w 6 n // unsigned
