IsRegularExpression()

Syntax

Result = IsRegularExpression(#RegularExpression)

Tests if the given #RegularExpression number is a valid and correctly initialized regular expression. This function is bullet-proof and can be used with any value. If the 'Result' is not zero then the object is valid and initialized, else it returns zero. This is the correct way to ensure than a regular expression is ready to use.
