>From the usual Z80 book:

JP cc,pq

byte1: 11ccc010
byte2: low part of addr
byte3: high part of addr

ccc maybe one of the followong

NZ     - 000
Z        - 001
NC     - 010
C       - 011
PO    - 100
PE    - 101
P      - 110
M     - 111

So if your assembler does not support JP P and JP M just replace them with
a .DB

JP P,addr = .DB 11110010b .DW addr
JP M,addr = .DB 11111010b .DW addr

If this occurs in a lot of places define some macros like the following

#DEFINE JPP(addr) .DB 11110010b \ .DW addr
#DEFINE JPM(addr) .DB 11110010b \ .DW addr
