Re: [amibroker] returning more than one array from a function

["Tomasz Janeczko" <amibroker@xxxxxx>]

Dave,

Yes but you should use global keyword inside function to make sure
it is treates  variables as global and you don't need to declare them before function call:

function SetTwoArrays()
{
   global staReturn1, staReturn2;

   staReturn1 = C;
   staReturn2 = ROC( C, -1 );

   return MACD(); // you can return 3rd array
}


SetTwoArrays();

//staReturn1 and staReturn2 variables are accessible there;

WriteVal( staReturn1);
WriteVal( staReturn2 );

Hope this helps.

Best regards,
Tomasz Janeczko
