John,
Some suggestions:
1. In the Init of the form, add the following code:

THISFORM.NewObject('oNumConverter','num2words','num2words')

2. Add a form-level method that calls:

lparameters tcnumber
THISFORM.textbox2.Value = THISFORM.oNumConverter(tcNumber)

3. Add the following code to the When method of the second textbox:

return .F.

1 gives you form-wide access to the new utility. 2 shows one way of utilitizing it to populate the second textbox. 3 makes it so users can not enter the converted textbox and change it. It is for display purposes only.

Good luck!
