A way to add an edit mask to an output field?

I have a table where one of the columns is numbers. They are actually dollar values. The customer would like it to display as $123,456 instead of 123456.
It appears that there is no way to apply an edit mask in ApplinX. Is there a way to do this easily?

Hi Bob,

This can be easily achieved by using the gx_changeControl Table user exit . Here
