You can apply the OVRPRTF command to all printer files by specifying *PRTF as the file name. The OVRPRTF command with *PRTF is applied if there is no other override for the printer file name at the same call level.
The following example shows how *PRTF works:
Override 1 OVRPRTF FILE(OUTPUT) COPIES(6) +
LPI(6)
Override 2 OVRPRTF FILE(*PRTF) COPIES(1) +
LPI(8)
CALL PGM(X)
