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.

I think you can....
try using "EXPR=", as in..
expr='make_some_var_name_here=do_this_operation'
ret=execute(expr)
note that what happens is that whatever you have after expr= gets
dumped to the command line as if you were typing it...I typically use
this method to create a series of arrays such as im1,im2,im3...,etc.
