local
LOCAL varname
LOCAL varnamelist
(LOCAL varname1 varname2 ...)
command. Accepts as inputs one or more words, or a list of
words. A variable is created for each of these words, with
that word as its name. The variables are local to the
currently running procedure. Logo variables follow dynamic
scope rules; a variable that is local to a procedure is
available to any subprocedure invoked by that procedure.
The variables created by LOCAL have no initial value; they
must be assigned a value (e.g., with MAKE) before the procedure
attempts to read their value.
