Hi,
i'd try the "confirm" command to determine whether a variable exists.
As for determining whether an ado has already been loaded, why not just
type:
. capture program drop p
that just drops it by brute force, but doesn't care if it hasn't been
loaded yet.
Or you could write similarly:
. capture drop x
that'll kill the variable in the same way.
Cheers,
-john.

Subject: st: inspecting loaded variables and programs
Dear all,
I am wondering what the stata-idiomatic way is to discover if a variable
"x" or a (non-.ado) program "p" is currently loaded. Sometimes in a .do
script I need to check if "x" and "p" already exist, and drop/replace
them if they do.
Thank you!
Pijus
