Re writing CL in RPG

Hi
Below is my code. I am trying to replace copy commands program by writing RPGLE.
Is this a good design , will this run faster? I would like to know your opinions and suggestions.
Thank you for your time. The number of records in AFILE usually more than a million.



LOOP: RCVF
MONMSG MSGID(CPF0864) EXEC(GOTO CMDLBL(END))

CPYF FROMFILE(*LIBL/ABC.FILE) +
TOFILE(*LIBL/XYZ.MONY) MBROPT(*ADD) +
INCREL((*IF MID *EQ &YID) (*AND +
MNAME *EQ &YNAME) (*AND MACCT *EQ &YACCT))
CPYF FROMFILE(*LIBL/AFILE) +
TOFILE(*LIBL/BFILE) MBROPT(*ADD) +
INCREL((*IF PID *EQ &YID) (*AND +
PNAME *EQ &YNAME) (*AND PACCT *EQ &YACCT))

GOTO CMDLBL(LOOP)

END: CPYF FROMFILE(*LIBL/ABC.FILE) +
TOFILE(*LIBL/XYZ.MONY) MBROPT(*ADD) +
INCREL((*IF MID *EQ F))
TOFILE(*LIBL/XYZ.MONY) MBROPT(*ADD) +
INCREL((*IF MID *EQ F))
CPYF FROMFILE(*LIBL/AFILE) +
TOFILE(*LIBL/BFILE) MBROPT(*ADD) +
INCREL((*IF PID *EQ F))
