Hello, New beta version has typeof() operator http://www.amibroker.com/guide/keyword/typeof.html
So you could use it that way:
if( typeof( variable ) == "undefined" )
{
}
If you rather looking for Nulls (which are semantically different than
undefined),
then use IsNull function. Best regards, Tomasz Janeczko amibroker.com On 2010-03-11 06:56, Mubashar Virk wrote:
