The minus sign is similar to the plus sign, but it applies trim() - not alltrim() - to the operand on the left only.
I remember having seen this in the help, but I can't tell you for sure, where. I never used it in actual practice, probably because only the first part is trimmed; so I didn't find it very practical. It does help, though, to make some expressions shorter.

The man whom I am to replace says that it hits the end of the data in the Loading.Desc field, rather than the end fo the filed, which would include the spaces after the data. Why is this not listed in the Help File, or was it in FPW 2.6a?
