FreeBASIC - Logical or: or, OrElse

Logical OR works as follows: just in case it's the result false if both inputs are false, in all other cases the result is true. In next table you can find all possibilities:
abx
FalseFalseFalse
FalseTrueTrue
TrueFalse True
TrueTrue True
information about the table: a, b are inputs, x is result

or

Description

par1 or par2
Used keywords: or

Input


Output

Both operands are evaluated independently of the value of the first operand.

Examples

FreeBASIC

In the source code you can find the equivalent of the above table, for easier orientation at the end of each line is a comment which shows the result.
a1 = false or false ' a1 = false
a2 = false or true  ' a2 = true
a3 = true  or false ' a3 = true
a4 = true  or true  ' a4 = true

FreeBASIC

Even one example in what situations we can use the operation logical or:
(b or c) or a
a or true
a>1 or a<100

FreeBASIC

Other pieces of example codes:
a or true
(10 >a or a<5)
j > 128 or false

OrElse

Description

par1 OrElse par2
Used keywords: orelse

Input


Output

If the first operand is true, then the second operand is not evaluated.

Examples

FreeBASIC

In the source code you can find the equivalent of the above table, for easier orientation at the end of each line is a comment which shows the result.
a1 = false OrElse false ' a1 = false
a2 = false OrElse true  ' a2 = true
a3 = true  OrElse false ' a3 = true
a4 = true  OrElse true  ' a4 = true

FreeBASIC

Even one example in what situations we can use the operation logical or:
(b OrElse c) OrElse a
a OrElse true
a>1 OrElse a<100
