Pay no attention to the man behind the curtain! I still say this
doesn't work for most cases, at least under Unix. The following is a
simple transcript to test thes, which shows how ROUTINE_NAMES crashes
when A is undefined, but works when A is defined.� In every case that
I tried (as noted below), the variable A needs to be defined at the
calling level *first* before ROUTINE_NAMES(STORE=) will work.

It could be that this works under v5.3, or on Windows. I don't know
since we don't have those versions around here.

IDL> .run
pro testset, name
void = routine_names(name,store=-1,findgen(10))
end
% Compiled module: TESTSET.

IDL> testset, 'a' ;; A is undefined here, and it doesn't work
% ROUTINE_NAMES: Variable is undefined: a.
% Execution halted at: TESTSET 2 /dev/tty
% $MAIN$
IDL> retall
IDL> a = 1
IDL> testset, 'a' ;; Now A is defined and it works.
IDL> help, a
A FLOAT = Array[10]

IDL> print, !version
