I am looking for a number to word function for the purpose of writing checks.

1633725.92 would be converted to

One Million Six Hundred Thirty Three Thousand
Seven Hundred Twenty Five dollars and 92 cents.

I noticed a NUM2ALPH program in the files -- but it is not for this purpose. I thought I had seen one written by Tom Rettig (I miss him) somewhere on the web, but could not find one. Any help
appreciated. Would need for it to go up to 999 million.
