Hi BW_Cummins,
There is no way to set an internal precision property of a DIAdem variable or a VBScript variable. You can of course format the display of that variable with the "str()" function, which you can include as an embedded expresion in a REPORT layout (text box, Axis lable, legend, etc.). You can also declare DIAdem real variables as either DBL or SGL, so that would set a certain maximum precision, but that doesn't sound like what you want.
Let me know if you need something other than display formatting,
