 |	description:							|
 |      -----------	This program replaces up to 20 occurances       |
 |			of "654321" in all files found in "SERIAL.DAT". |
 |			The string "654321" is replaced by a serial	|
 |			number.  Leading zeros will be filled in by	|
 |			the program.  The starting and ending serial	|
 |			number's are read in from the command line.	|
 |			The user is prompted for the serialization	|
 |			drive.						|
