Microsoft® Visual Basic® Scripting Edition CBool Function  Language Reference 
Version 1 


Description
Returns an expression that has been converted to a Variant of subtype Boolean.
Syntax
CBool(expression)

The expression argument is any valid expression.

Remarks
If expression is zero, False is returned; otherwise, True is returned. If expression can't be interpreted as a numeric value, a run-time error occurs.

The following example uses the CBool function to convert an expression to a Boolean. If the expression evaluates to a nonzero value, CBool returns True; otherwise, it returns False.

Dim A, B, Check
A = 5: B = 5            ' Initialize variables.
Check = CBool(A = B)    ' Check contains True.
A = 0                   ' Define variable.
Check = CBool(A)        ' Check contains False.
