🚀 go-pugleaf

I have a test version of an application (no name can be cited) that will save
a text version of it's documents.  Unfortunately, it types them DATA not TEXT
so I have to use something like Developer's Tools to change the type before I
can get any other application to read these files.  If I do this, the 
application's DATA document icon is replaced by the generic TEXT icon.  I would
like to have an application specific TEXT icon. 

I used ResEdit to add my new icon to the ICN# resource of the application, and
to add an FREF by copying the one for DATA and changing the type to TEXT. I am
not sure its correct, but I used the zero based index of my icon in the ICN# as
the local icon #.

Anyways, this doesn't seem to work, I still get the generic Icon.  Can anybody
tell me how to do what I want to do, or what I am doing wrong?

Thanks in advance
