RE: [amibroker] Database specification - command line? xx.js listing

["J. Biran" <jbiran@xxxxxxxxxxx>]

How does one use this xx.js Java script?

Does anything else besides the path to database and
ticker symbol need customizing to open a different database?

So it might be like this (xx.js):
NOTE that I have no experience in windows scripts nor have not chacked
this 
code.

=========
/* GB: The path to database */
DataDir  = "G:\\Amibroker\\Data\\Parkiet_EOD";
/* GB: The ticker to check */
ChkTicker = "TPS";

/* Create AmiBroker app object */
AmiBroker = new ActiveXObject( "Broker.Application" );
/* ... and file system object */
FileSys = new ActiveXObject( "Scripting.FileSystemObject" );
WshShell = new ActiveXObject( "WScript.Shell" );

function IsValidDatabase()
{
	AmiBroker.SaveDatabase( );
	AmiBroker.LoadDatabase( DataDir );
	if( AmiBroker.Stocks.Count > 0 )
	{
		try
		{
			return AmiBroker.Stocks( ChkTicker ).Ticker ==
ChkTicker;
		}
		catch( e )
		{
			WScript.echo("The database currently loaded
into AmiBroker does not have " 
+ ChkTicker + "\nSo I guess this is not correct database.\nUpdate
failed.");
		}
	}
	return false;
}

function Main()
{
	bOK = true;
	if( ! IsValidDatabase() ) return;
}

Main();
