>I have a legacy Visual FoxPro 6.0 application where I need to do a simple multiplication where one of the terms have more than 4 significant digits. I have tried the following code, but this has no affect whatsoever:

Some SET commands are scoped to the current datasession, meaning that you may have to set them at a specific form.
If the result is as if nLabor were rounded to four decimals, that looks as if some of your data might be of type Currency. Check this, and if necessary, convert to numeric with mton() before doing the calculation.
