> cheers TomTCL/TK is being used in many applications, including GRASS. Any
application that can be used on the command line or a script can easily
be implemented.but I have made a basic vis tool for several specific applications.
It is also amenable for use in integrating GRASS to database
applications. In particilar, I made a specific tool that uses
INFORMIX directly and GRASS for spatial queries.Of course this could be done on the C level as the inf tools
but I would not know about C....If you are serious about TCL/TK you may want the manual though...

I was really wondering if anything had been arranged to coordinate
effort in the GRASS community. If a lot of people are using tcl
and tk with grass then, I suspect, a lot of wheels are being
re-invented. So far, in the limited amount of tcl experimenting
I've done, I've had to implement the equivalent of;
G_gisdbase, G_location_path, G_mapset, G_find_file and G_ask_old
in order to make one listbox from which to select a GRASS file.
