define
DEFINE procname text
command. Defines a procedure with name "procname" and text "text".
If there is already a procedure with the same name, the new
definition replaces the old one. The text input must be a list
whose members are lists. The first member is a list of inputs;
it looks like a TO line but without the word TO, without the
procedure name, and without the colons before input names. In
other words, the members of this first sublist are words for
the names of required inputs and lists for the names of optional
or rest inputs. The remaining sublists of the text input make
up the body of the procedure, with one sublist for each instruction
line of the body. (There is no END line in the text input.)
It is an error to redefine a primitive procedure unless the variable
REDEFP has the value TRUE.
