The issue with a GNU project is that GNU is more than just one program.  
It's an entire operating system, usually using the Linux kernel.  And of 
course, the GNU project has an editor: Emacs.  This editor has a "locate" 
functionality, which is supported by a TAGS file.  vi also has this feature 
(the file for vi just is in lower case: tags).  Since most people using 
Emacs don't develop in an interactive language, that way is better for them.

To make use of this feature, we added creation of TAGS and tags files to 
Gforth.  That's the way Gforth stores information about where a word is 
located; that's the way which works best with these Unix editors.  Other 
editors on Unix often support either one or the other format.

If you think that's not how things work under Windows: Yes, it's not.  It's 
also not the way traditional Forth works; probably because the poor C 
compiler users can't say "locate xxx" on their C prompt ;-).  But just 
because you are unfamiliar with something doesn't make that a bad thing - 
staying in the editor while jumping from one to the next definition is fun; 
before I could only have that with an embedded editor (which I had in 
bigForth).  Anyways, as GNU maintainer, I have to tell you that we don't 
recommend proprietary operating systems and editors ;-).

The locate feature is relatively new, so we certainly welcome suggestions - 
the point of snapshot releases is to get feedback.  A embedded information 
about the location of a word as described above would help with editors that 
don't support any tags file, as well as with a possible embedded editor - 
I'm thinking about writing such an editor, as the users on Android (and 
probably also Windows ;-) don't have a nice integration with a good 
programmer's editor.
