Limit Form field data entry

Hello.

I want to limit form field data entry to numerical values(no minus values) but I am able to have minus signs entered The form field is a STRFILLIN

here is what I have used:

(case VCF->curField

  ("space_1_x_spaces"

   unless(forall(nStr, parseString(VCF ->curValue), rexMatchp("^[-]*[0-9]*[.]*[0-9][0-9]$", nStr))
    axlFormRestoreField(VCF, VCF ->curField)
      )))

I though that the ^ was a negation.

Thanks in Advance

There are many ways you could do this - but why not use a real number form field in the first place and set the lower limit to 0?
If you really must accept a string then a valid test (for a positive real number) might be:
rexMatchp("^[0-9]+[.][0-9]+$", VCF ->curField)
The "^" character at the beginning matches the start of the string - the "$" matches the end.

Thanks Dave,

I am using a STRFILLIN because I want the users to be able to enter many real numbers at once in the same field.

I would like it to be limited exactly the same as the grid spacing Set up menu in APD
- Multiple real numbers in the same field.
- Only positive real number
- With or without decimals.

Can I use a logical operator with the rexMatchp to have more then one match possible?

Dave,
Here is what I have used "^[0-9]*[.]*[0-9]*$"
It does what I need.
Thanks
