DLL- application link
 

How can I link a fortrand application to an excel
worksheet?
I'm constructing a model in excel. The fortrand
application is supposed to receive an input file with a
serie of data. The model-user is inserting those data in
the excel worksheet and they should go as input to the
application. The results from the fortrand application
should be reported in excel as well.
I know how to make the ddl file but how to link it then?
I hope someone can help me!
Thanx in advance!
