[amibroker] Re: How to pass variables from AFL to embedded JScript?

["ozzyapeman" <zoopfree@xxxxxxxxxxx>]

And if there is no way to pass variables directly from AFL to JScript,
can I first fput the AFL vars to some kind of log file, and then is
there a command in JScript that can pull those vars to use for the
Dates?

I can also use VBscript, if that makes any difference. I'm just not all
that knowledgeable about either J or VB scripts.
