| I would like to have some "global variables" remain alive even after the

| there a better way to serve the same purpose?


Here is how I would solve the problem. This is like our config files for
Windows and Lanman. 

I would create a file called GLOBAL.INI which is pointed to by an
ENV variable called HOME or INIT. I would write generic routine to
read and write from the tags in the file. The structure of the file 
would be like.

[Program-1]
   var1=szTag
   var2=1
   var3=Color

Then when you run your program you can use your routine to access from
init file. If you ever port your software to windows or PM your code won't
have to change much. Look at the call GetProfileString() in a book
about windows program to give you an idea.
