if A > B then ...

if A > 47 then ...

if A + B > A ...

First, compiler evaluates the expression on the left. During runtime, result is stored

in a variable of type that matches the largest data type in the expression. In this

case it is byte, as variables A and B are both bytes.

This is correct if the value does not exceed range 0..255, that is, if A + B is less

than 255.

Let's assume Aa is of word type :

if Aa + B > A ...

First, compiler evaluates the expression on the left. The result value is treated as

type that matches the largest data type in the expression. Since Aa is word and B

is byte, our result will be treated as word type.

This is correct if the value does not exceed range 0..65535, i.e. if Aa + B is less

than 65535.

' if tC is less than zero, tC = -tC

if tC < 0 then

tC = -tC

end if

' Stay in loop while C is not equal to variable

' compare_match; increment C in every cycle

while tC <> compare_match

tC = tC + 1
