Well I have a C program to do this.  It was written in an introductory C
class, so it isn't too fancy.  But the concepts might help.  I know it
isn't RPG but it might be worth a look anyway.  Cut and pasted below.
Copy the three source files below into numbers2words.c, functions.c, and
functions.h respectively and compile with something similar to:

gcc -Wall -c numbers2words.c
gcc -Wall -c functions.c
gcc -o numbers2words numbers2words.o functions.o

(of course on iSeries the compile commands are different)

/*This program prints out the English equivalent of a

  two hundred eighty-seven thousand five hundred eighty-one
