Booth,

The following OPNQRYF does what you are attempting to accomplish by
substringing part of a field into another for sorting(i.e. Key Sequence)
The field being mapped into can only be used for input.

 /* The OPNQRYF remaps the area code & prefix portion of the billing + 
    phone# to BDAD1B so that the key will be the area code and       + 
    phone prefix.                                                   */ 
 OpnQryf File((BDMASTP)) Option(*INP *UPD) +                          
         QrySlt('bdplby *eq "SUN"') +                                  
         KeyFld((BDAD1B)) +                                            
         MapFld((BDAD1B '%SST(BDdnam 1 6)')) 


Hope this helps!!
