Invoking a COM object method, that results in two arrays [message #61304]

Hello!

Currently I am successfully using a function of the library
XtremeFringe (http://www.iot.es/XtremeFringe/index.html) in IDL 7.0 by
instantiating a COM object and then invoking its method with the needed
parameters. The corresponding code looks like the following:

------------
; generate COM object
MyXtremeLibObject =
OBJ_NEW('IDLcomIDispatch$CLSID$IDENTIFIER_FROM_WINDOWS_REGIS TRY')

; invoke the function
resulting_array = MyXtremeLibObject -> THE_FUNCTION(some, para, meters)
------------

This works for a function, that results in just one single array.
But in the case of a function resulting in two arrays it does not.

------------
# invoke the method
result2 = MyXtremeLibObject -> THE_SECOND_FUNCTION(some, para, meters)
------------

In this case the variable result2 has only two elements with zeros in
it:
result2[0] => 0.0
result2[1] => 0.0

Maybe these elements could be something like pointers to the addresses
of arrays, but I did not find a way to use it in IDL.
In Matlab one gets the results in a cell array by something like

------------
result=XFLib.The_Function(some, para,meters);
resultarray1=result{1};
resultarray2=result{2};
------------

In IDL I do not know how to do it in a similar way.

I would be happy, if someone can give me a hint for solving my problem.
Best regards

Karlo
