Spooled file problem

To all the OS/400 Experts:

We have a real urgent operational problem here.  When you do a WRKSPLF
command and hit F11 twice, the first two columns are *File* and *File
Nbr*.  The File Nbr field is evidently four bytes long; it seems to
increment by spool file name (i.e., QPrint number 1, QPrint number 2,
QSysPrt number 1, etc.).

The _pressing_ problem we have here, is that we have a lot of save
spooled files with the same name (for example, Invoices), which is
causing this four-digit number to "top out" at 9999.  We have a utility
which takes the spooled file and turns it to ASCII for pretty print, but
this utility BOMBS when the high number is reached.

Question:  Can we reset this number (for a given spool file) without
having to IPL or something?  IPL at this time is not an option.

Please help if you can!

Sincerely,

Richard C. Hart
