Subject: Re: DDS screen: how to ensure field keyed is numeric for alpha-descri bed field
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.
