Bool

Language reference

Syntax

result = Bool (expression)

Description:

Converts any type of value to boolean. Boolean is an expression that evaluates to either True or False.

Examples:

' String that contains any characters is converted to True
b = Bool ( "Hello" )

' Blank string is converted to False
b = Bool ( "" )

' Number is converted to True if one is nonzero.
b = Bool ( 21 )
b = Bool ( 3.14 )
b = Bool ( -5 )

' If value contain zero is converted to False
b = Bool ( 0 )

' By the Bool() you may easy test if string is blank
string = "Hello World"
If Bool(string)
 MsgBox "String contains any characters."
Else
 MsgBox "String is blank"
Endif

In fact you doesn't need Bool() because LC Basic automatically converts any values in the logical expression. So that you may use right:

string = "Hello World"
If string
 MsgBox "String contains any characters."
Else
 MsgBox "String is blank"
Endif

Using Bool() as command has not effect. vis. Functions

String = "Hello"
Bool (String)
String is still "Hello"

AND operator, OR operator,XOR operator,NOT operator,  If, Else, Endif
