st: c(filename), quotes

[Laura Gibbons <gibbonsl@u.washington.edu>]

I'm running Intercooled Stata 8.2 on Windows.

I have 2 related questions about how to create a macro that contains the 
name of the open file, and then how to set up the quotes to access that 
file later.  Here is a simplified example:

. use actthetawide.dta, clear
. global origdata c(filename)
. di $origdata
actthetawide.dta

. clear
. use $origdata
invalid '('
r(198);

Does anyone know why the error message?

Secondly, in real life there will usually be a path name that contains 
spaces, so my program will have to put quotes around the file name.  I'd 
like it to interpret

.use (some quotes)$origdata(other quotes)

to mean

use "actthetawide.dta"

but no matter what combination of quotes I try, I can't get the filename 
to display inside the quotes.  I get back "c(filename)"  or "$origdata" or 
some such nonsense, depending on what I do.

I searched the manual and the archives to no avail, so I'm hoping you can 
help!

Many thanks, Laura
