The problem is that many of the DDS functions, like CHECK, will not work with UPDDTA. IBM explained this to me years ago that the 400 adopted the Least Common Denominator between the S/38 and the S/36. Alas, the S/38 didn't have some of the functions that the S/36 did with IDDU. One radical idea is to create yet another file. Store all possible values in this file, like '000001' through '999999'. Then do a ADDPFCST from your customer master file to this file. This will be supported by: traditional, UPDDTA, C/S, web...

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
