# 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

### Output

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

### 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

### Output

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

### 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``````
