numeric numbers to alpha strings.

Hello. Are there any conversion routines around for changing numeric dollar amounts to spelled out strings for putting on checks? I wrote a quick basic routine a long time ago. It took any number such as '125.32' and created a string 'one hundred, twenty-five dollars and 32 cents'. It works just fine for amounts up to 20 or 30 thousand but I thought there might be this nice little function out there somewhere. TIA Floyd --
