Re: [amibroker] Help: MetaStock's IsDefined

[Tomasz Janeczko <groups@xxxxxxxxxxxxx>]

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,
