Local static variables.

[Tom Enebo]

SOS,

I would like to be able to define a variable in Emacs-Lisp that
is local to a function, but does not lose it's value when the functions
exits. I know I can create a local variable via let, but any local
variables within let are disposed upon exit of let.

Any suggestions are welcome,

-Tom

$|=1;for("!","E","M","O","T"){print $l=$_.$l,"\015";sleep 1;}

You can't do this in Emacs Lisp, it doesn't have local static variables or
lexical closures. You have to use a global variable.

If getting object oriented is a viable alternative, try the Eoops
package.
