Now that worked but now I modified it and it doesn't work.  Here is the new code:

temp0 VAR Byte
temp3 VAR Byte

Start:
  LOW Solenoid
  LOW Fan
  LOW Alarm1
  LOW Alarm2
 
Main:
  temp0 = Flow + Temp
  temp0 = temp0 + ~Gas
 ' temp0 can ONLY be 0 if Flow=0, Temp=0, and Gas=1 alarm dange level

  temp3 = Flow & Temp
  temp3 = temp3 &  Gas
 ' temp1 can ONLY be 1 if Flow=1, Temp=1, and Gas=1 alarm dang level rising

  
  
  IF temp0 = 0 THEN
    Solenoid = 0
    Fan = 1
    Alarm1 = 1
    Alarm2 = 0
 IF temp3 = 1 THEN
     Solenoid = 1
     Fan = 0
     Alarm1 = 0
     Alarm2 = 1 
  ENDIF
    Solenoid = 1
    Fan = 0
    Alarm1 = 0
    Alarm2 = 0 
  ENDIF
 
  
  GOTO Main

 

Any Help is greatly appreciated.
