Our database cust# is an alpha field, but we only want to allow numeric entries into the field.
What is a good way to ensure data keyed into a field is numeric using DDS screens?
I can't chain to the cust file in some cases because ranges are allowed, for example two fields exist on the screen to key a start cust# and an end cust#.
Also, I dont want to allow an entry such as "0 0 0" (problem, spaces in between).
What is the simplest way to accomplish this?
TIA
