'''~''' a.k.a. '''not''' is usually used in conjunction with an [[If]] [[statement]].

Don't use NOT, use ~ because it will work everywhere whereas NOT will only work in If statements

----

1) The tilde character is "not" in BR: '~'

If ~1 then print "X" else print "Y"
Y

In my testing, "NOT" only works in an IF statement or a PRINT statement. Whereas "~" works everywhere.

let X=1
let Y=NOT X ! Gives an error
let Y=~X ! Sets y to 0
print NOT Y ! prints 1
print ~X ! prints 0

2) Keep in mind that you can use the unary operator "NOT" in many more places then in an IF-THEN statement. So it couldn't be a parameter of the IF statement.

You can do a comparison and assign the results to a boolean variable (in BR thats just a regular numeric variable that you're calling a boolean variable).

let A=5
let B=7
let TEST = ~(A>B)
IF TEST THEN PRINT "X" ELSE PRINT "Y"
X

You can also print the results of a conditional statement:

PRINT NOT (A>B)
1
PRINT ~(A>B)
1

So, in my testing I have discovered two important things:

1) NOT and ~ do the same thing. But NOT works in only IF and PRINT statements whereas "~" works for IF, PRINT, and LET statements, as well as Function Call Parameters, and many more places.

2) There are lots of different places you can use NOT (~) and all of them are useful.
