Create a custom MASK

How do you create a MASK for a BPM 7.6 text field that will accept only numbers in the format of:

9

99

999

9,999

99,999

999,999

9,999,999

99,999,999

999,999,999

I have been trying to reverse engineer the Masks that are displayed for SSN, TIME, etc., with no positive results.

Thanks.
