As the character "\" is escape sequence for line continuation, we have to put two "\" chars. This will avoid compilation error.
Still no luck when adding to data files. When I do this the compile error stating that the file cannot be found goes away. Now I am getting an error stating that the file cannot be opened. I know that the file can be opened because when I go back to using the full path things work fine.
My System > Directory settings are the defaults that are installed with Silk Performer. I am not really using this directory. I have my include file in the same directory as my script but other include files in subdirectories. I am just being one of those oddballs and looking at ways to manage our scripts in assocation with how the application is structured.
Where is your bdh file located? I believe that the only place SP will look for include files are either in the include directory (which defaults to C:\Program Files\Segue\SilkPerformer 5.1\Working\Include\) or in the project directory for your current project.
To include something that is not in either of these folders, use this...
replace C:\\Program Files\\Segue\\.. with whatever the drive letter and path that the productsetup folder is in.
Try that. It should work, I just tried it. I hope that works, I would hate to be embarrassed!
