Paul,
a backslash is an escape character in Stata. In front of a local
macro, a backslash prevents execution. I.e., - \`x'- becomes `x' after
Stata executed the line. This can be useful in programming.
For your problem, try replacing the backslash with a forward slash. At
least in Windows this works fine. I don't know about other operating
systems.
