The underlying problem here is that the -save- command doesn't allow a 
variable list (of -if- or -in-, for that matter). But -outsheet- and 
-outfile- do.  Alternatively, if the user has some writeable local storage 
STATATMP can be set by the user to point there, and that would speed up 
-preserve-, -restore- and many other commands.
