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
Define the customer # fields on the screen as numeric. Do all the
checking (e.g., "from" is not greater than "to",
range checks, etc.) on these numeric fields. THEN move the numeric
fields to alpha fields to actually USE as customer # in your
application.
