Henrik, for my edification is this the correct answer? Please don't roll your eyes too far if this is too much of a NOOB question.
IF SWITCH = 1
IF SWITCH = "1"
IF SWITCH = $31
IF SWITCH = 49
IF SWITCH = 1 checks to see if SWITCH is set to ON
IF SWITCH = "1" checks to see if SWITCH is equal to an string value of 1
IF SWITCH = $31 checks to see if SWITCH is an ASCII 1
IF SWITCH = 49 checks to see if SWITCH is an ASCII 1

For the life of me I cannot discern the difference between the last two. $31 = 49 on the ASCII table. How are they different?

Thanks for your patience.
