You can access Main Level Variables!!!

[Michael Lefsky <lefsky(at)fsl.orst.edu>]

So it turns out you can access main level variables- try this

create this function:

function fetch,string
var=routine_names(/fetch,string)
help,var
return,var
end

then

dummy="hello"

print,fetch("dummy")
VAR             STRING    = 'hello'
hello

So one could do what I want- create a new "foolproof" save command.  Now
if we just had a way of executing statements as if they were type at the
main level.
