Yes, just make sure you use double back-slashes like any other string.
"C:\\EUPHORIA"

As of yet, no. But I'm looking into eudir and include working in any
level of code, if, for, while, procedure, function, type, etc..

This was actually my suggestion, so yes. I actually forgot about it.
It will be in the next release.

You must explicitly call, or have called routine_id() or variable_id()
at one time. The reason is that the routine id list and variable id
list are not the same as the symbol table. routine_id() adds your
routine to its internal list and returns the index (starting from 1),
and the same for variable_id().

Scope is not affected. You can call variable_id() inside a procedure
or in another include file. You just won't be able to read/write the
variable once it no longer exists. I am working on a way to determine
if a variable_id() is valid or not.

I'm still learning... there's a few things I don't understand about
the interpreter yet. I'm sure my variable_id() will cause some issues
with variables that are no longer used and such, but I'm getting
there. The more features I add, the more easier it gets. And yes,
"more easier" is a technical term.  :)

Truthfully, this all comes out of my own selfishness. I wasn't going
to share my new interpreter at first, but I figured why not? Somebody
needs to give everyone the features they want!
