A separate program, LSPEDIT, provides a very simple Lisp file
editor.1 Like the listener, LSPEDIT supports parenthesis
matching and code indentation. In addition, the Edit menu in
LSPEDIT contains an item for pasting a selected expression into an XLISP-STAT
application. This is accomplished using the Windows Dynamic Data
Exchange (DDE) mechanism. It seems to work with one instance of LSPEDIT
and one of XLISP-STAT running. In theory, it should also work if there are
multiple instances of LSPEDIT running. It would get very confused if
there were multiple instances of XLISP-STAT, but the current version does
not allow this.
