DSPF numeric field editing

I've searched the archives but have been unable to find any previous reference to this issue.

I have a DSPF with a numeric field (11,4) where the user is allowed to key in a number with or without a decimal point. If they key in a decimal point, then the program takes that number as the actual value. If not, then the program assumes 4 decimal places and divides the entered number by 10,000. (Please don't ask why - I've fought that battle and lost. Yes our users are still in the dark ages.)

So far, so good.

Let's say they key in the number "2" and press Enter. The program will assume four decimal places and divide by 10,000.

So far, still good.

If there are no errors or messages, the program will go back to the first screen and allow the user to select another record to be updated. But if there is an error or message (my message, not system message) the program loops around and does another EXFMT and the number shows up exactly as they keyed it in, ignoring any editing, even though the value is correct (0.0002, verified in Debug). I've tried an edit code and an edit word - neither works.

Is there some kind of quirk with a numeric display field that ignores any editing if there's an ERRMSG on?

Here is the field DDS:

A FUTPRC 11Y 4B 14 28COMP(GE .0000)
A DSPATR(PC)
A EDTWRD('0 . ')
A 41 ERRMSG('Price Below Cost. Press F5-
A to override.' 41)
A 42 ERRMSG('No Cost Available' 42)
A 49 ERRMSG('Both fields are required' 4-
A 9)
A 40 ERRMSG('Abnormal price - press ENTE-
A R to accept.')
A 40 COLOR(RED)


Please help... I now have a dent in my wall, and a headache.

TIA,

Tim
