That does what I want it to do, so thanks for that suggestion. What do
those cascade names become assuming the foreach brings back directory

Hmm..
Tcl/Tk is very simple. But some reading man pages (in this case, menu)
still helps.

As my (maybe too brief) explanation showed, to add a cascade you'd best
specify a new menu. How to call this is up to you - just make sure its
name doesn't start with an uppercase letter (that's why I put a "m" in
front).

You can call [glob] separately for subdirectories (-type d) and files
(-type f). I'd suggest first to do the directories, create a cascade
for each,

.m.whatever.m$dir create cascade -label $subdir -menu [menu
.m.whatever.m$dir.m$subdir]

and recurse into them (call the same procedure for each again). Then do
the files, adding a simple command to the current menu.

general approach is dead on, but be *very* careful using externally
generated names (like filenames) directly as component of widget names,
if they contain a . you will blow up as the . is the widget seperator.
so I would either keep a simple 1-up counter to make the menu widget
name itself (keeping the displayed label the actual directory) or else
use string map to map any "." to "_" or something (and mayber spaces
too which don't necessarily break you but can cause headaches occasionally.

Yes, I am not sure what I want to do here. The file format is going to
be a set one. I may create a simple ini file with something like
title=blah as the key/value then a user would just have to drop in the
file and update the ini file and I only have to parse that. Come to
think of it that is what i will do. It saves me from having to do
globbing and such to get directory and file names. I can use the
key/value to get the file name and title of the lesson and I can use
the section to denote the directory it resides in. I could even build a
wizard in the app to help create the ini section itself.

Hmmm, I will try that.
