Display file Field

[mksamy_99]

Hi,

I have display file field say 'Name'. I have defined as Alpha numeric. Now in this field I should not enter Numeric Values. If I enter the field should not accept the value and need to through an error.

Since the field is defined as 10 A it is acceting the Numeric inputs also. Now the question is how to restrict the Numeric Values? It needs program level change of Display file level Change?

Thanks
Muthu

Hi mksamy_99

From the DDS Reference...Display files
http://publib.boulder.ibm.com/iserie...f/rzahfms1.htm under "data type"

Alphabetic Only (X)

Both types of keyboards are in lowershift. Only the characters A through Z, comma (,), period (.), dash (-), and space ( ) can be typed in. When you type lowercase characters a through z, uppercase characters are sent to the program. See CHECK (Check) keyword for display files for an explanation of how to permit typing in lowercase characters for the typewriter-like keyboard on the 5250 work station.

Best of Luck

Re: Display file Field

I've always preferred checking the data in the program (like Jamie's example) rather than thru the display file in these situations. Since the field in the file can be updated via other methods than simply the display file, you'll need to be able to monitor / control those other methods as well.

Agreed ..... Just pointing out an alternative

Re: Display file Field

How about of using field level RANGE keyword in display file?

first let me say...why are drudging up posts that are months old?

secondly, validating on the display file itself is a major irritant to most users (and myself i absolutely HATE DDS validation). why inhibit the screen, require hitting reset, and force your users to squint at the status bar on the emulator?) using a MSGSFL or a simple message field on the screen itself is much better IMO. easier on the eyes (especially for those of us with bad eyesight), less keystrokes, able to display a much more descriptive message, etc. i wouldn't recommend using DDS validation for anything at all, users get confused enough already.
