  Something like:
  

          mov    flag, #0
          ...
          ...
          cmp    flag, #0  wz
    if_z  cmp    Pin_7, #1  wz
    if_nz jmp    #:elseif
          mov    flag, #1
          ....
          ....
          jmp    #:end
  :elseif cmp    flag,  #1  wz
    if_z  cmp    Pin_7, #0  wz
    if_nz jmp    #:end
          mov    flag, #0
          ...
          ...
  :end

  I think this might work, too:
  

  cmp     flag, #0                wz
                          test    p7mask, ina             wc
          if_z_and_c      mov     flag, #1
          if_nz_and_nc    mov     flag, #0
  

  
  Still, value in flag could simply follow what's on P7 -- unless flag is able to have a non-zero value other than one (and if that's the case, my code is bogus).
