Mnemonic Operand Operation Description
NOP IP = IP + 1 No operation is done.
NOT TOS = NOT TOS
C = 0
IP = IP+1 Change TOS to its one's
complement.
OR
TOS = TOS OR [DSP--]
C = 0
IP = IP+1 Bitwise OR of TOS and NEXT.
Drop NEXT.
OR #literal TOS = TOS | LITERAL
C = 0
IP = IP+2 OR literal with TOS.
OR_R TOS = TOS OR [DSP--]
C = 0
Return Bitwise OR of TOS and NEXT.
Drop NEXT. Return to caller.
POP absolute
address
[absolute address] = TOS
TOS = [DSP--]
IP = IP+3 Pops TOS and stores it at the
absolute address.
POP !D [BP+D] = TOS
TOS = [DSP--]
IP = IP+1 Pops TOS and stores it at the
BP plus displacement address
D.
Displacement range is 8..23.
POP !TOS [BP+TOS] = [DSP--]
IP = IP+1 Pops next element and stores it
at the BP plus TOS address.
TOS unchanged.
POP [PTR] [D] [[BP+(PTR*2)]+D] = TOS
TOS = [DSP--]
IP = IP+2 Pops TOS and stores it at the
address held in 2-byte pointer
PTR plus unsigned
displacement D of 0 to 255.
POP [PTR] [TOS] [[BP+(PTR*2)]+TOS]=[DSP--]
IP = IP+1 Pops next element and stores it
at the address held in 2-byte
pointer PTR plus TOS address.
POP CPUREG CPUREG = TOS
TOS = [DSP--]
IP = IP+1 Pops TOS and stores it in the
specified register.
CPUREG = FLAGS, RSP, DSP
