TIA Portal underscore seperator?

I have an issue in TIA Portal that I cant find an answer to. I build out a unique identifier for faulting per our companies software standard by using a stationID, ComponentID, FaultedState and Fault Number. The equation is dne using a calculate instruction (((IN1 * IN3) + (IN2 * IN4) + IN5) * IN6) + IN7. As long as the result is 8 digits everything is fine, but as soon as I go to 9 digits then I get an "_" seperator. example:
IN1 = StationID = 10
IN2 = ComponentID = 10
IN3 = 1000000
IN4 = 10000
IN5 = FaultedState = 5020
IN6 = 10
IN7 = Fault Number = 1

The expected result is 101050201, but I get 101_050_201 instead of 101050201. The underscores stay when I convert this value to a string for display purposes. Does anyone know what causes this or how to change this behavior?

Thanks,

Can you post a screen shot showing your problem - this is what I get:

i think he means the 1000 separator is an underscore and is trying to get rid of it in his output

dhullett08, post your code.
And what is your CPU ?

It just dawned on me that maybe are are doing this in a Script in WinCC rather than in code in an S7 PLC.
And if so, WinCC Advanced or WinCC Professional ?
The "_" may be a setting in Windows that affects your VBS or C script.

Describe what you have done in detail.
