True and False (Advanced)

When a comparison is made, it produces a true or false value, like 2 + 3 produces the value 5. The reserved word "false" is just another way to represent the integer 0, and likewise "true" is equal to -1 (=$FFFF).

Using these concepts and adding the new variable High, the previous example from the GUESS program can be rewritten as:

        High:= Guess > Number;

        if High = true then Text(0, "Too high")

        else Text(0, "Too low")

Going one step further, since High is assigned either true or false and since:

        true = true    is true

and:

        false = true    is false,

the "if" statement can be simplified as:

        if High then Text(0, "Too high")

        else Text(0, "Too low")
