JPO
Operand:
label
Short Jump if Parity Odd. Only 8 low bits of result are checked.
Set by CMP, SUB, ADD, TEST, AND, OR, XOR instructions.
Algorithm:
if PF = 0 then jump
Example:
include 'emu8086.inc'
#make_COM#
ORG 100h
MOV AL, 00000111b ; AL = 7
OR AL, 0 ; just set flags.
JPO label1
PRINT 'parity even.'
JMP exit
label1:

exit:
RET
