I'd like to thank those who offered help with my problem of how to "save" a file equation for later use.
 
The problem was how to come up with a way to save a file equation for a report, the parameters of which the user would enter (ldev, copies, priority). This was necessary since within the job that this report would print is a following file equation for printing forms (checks). Other reports - that would use the print settings the user had entered - would follow the checks. This is when the job would re-use these settings.
 
Reid's was on the mark. Here's what I ended up with:
 

!JOB 

!FILE APPRINT=JAP301 ;DEV=LP ,08,001 (these are the settings entered by the user)

!FILE FILEQ = FILEQ;MSG

!LISTEQ > *FILEQ

!WHILE FINFO("FILEQ",19) > 1

! INPUT PRINTER < FILEQ

! IF STR("!PRINTER",7,7) = "APPRINT"

! SETVAR PRINTER_POSITION POS("DEV=","!PRINTER",1)

! SETVAR PRINTERNAME RTRIM(STR("!PRINTER",26,10))

! ENDIF

!ENDWHILE

!SHOWVAR PRINTERNAME

!PURGE FILEQ,TEMP > $NULL

!RESET FILEQ

!FILE APPRINT=CHECKS;DEV=MIS1,1

!RESET APPRINT

!FILE APPRINT=JAP301;DEV=!PRINTERNAME

!EOJ
