HELP WITH SOME Nbit MATH

[pedja089]

Look at this:

MATH_CMP  macro Zin, Xin    ; Compare Pvars - result in M_EQ and M_GTE bits
    MOVE?PP  Zin, REG_Z          ; Z <=> X -> STATUS(C,Z)
    MOVE?PP  Xin, REG_X
    CLRFSR                       ; clear FSR first
    L?CALL   M_CMP
    MOVE?TT  STATUS,Z, _M_EQ     ; STATUS,Z set if Z == X
    MOVE?TT  STATUS,C, _M_GTE    ; STATUS,C set if Z => X;
  endm

If I understand Darrel's code then:

• If Z and X are equal you have set M_EQ and M_GTE
• If Z is greater than X, bit M_GTE is set, bit M_EQ is 0
• If Z is less than X, M_GTE and M_EQ are 0

EDIT:
PBP code should look like this:
IF M_EQ=1 AND M_GTE=1 THEN
'Z = X
ELSEIF M_EQ=0 AND M_GTE=1 THEN
'Z > X
ELSE 'M_EQ=0 AND M_GTE=0
'Z < X
ENDIF
