Sorry, but that's wrong. CDPATH defines a list(!) of directories where
Gemini should search for the directory given as argument in the cd
command. It's something similar to the PATH variable, which gives a list
of directories where Gemini should search for the given command. I'll show
you an example, perhaps you'll understand it more easily:
Imagine you have a folder structure like this:
c:\btx\
c:\btx\macros\texts\
c:\btx\macros\grphics\
c:\btx\pages\german\
c:\btx\pages\englisch\
c:\fido\
c:\fido\out\ 
c:\fido\in\
Now suppose you are currently working in d:\fido\out and want to change
into c:\btx\macros\texts\ to examine a text. Normally, you'd have to type
in the full path in order to get there. If you are using CDPATH, you can set:
setenv CDPATH='.,c:\,c:\btx\,c:\btx\macros\,c:\btx\pages\,c:\fido\,d:\' etc.
Now all you've got to type is "cd texts" and gemini will cd to 
c:\btx\macros\texts. Got it? This is very powerful tool, you'll save a lot
of work, especially if you would normally be forced to use long paths...
The list in searched from left to right, so it's a good idea to put the '.'
in first place. Thereby Gemini will search in the current directory first.
/s/
PS: Are You using the english or the german version of Gemini? Take a look
    at mupfel.doc, they explained the reason for CDPATH quite good.
