Re: Toggle appointment notification

[daniela-spit@gmx.it]

I have gone into appt-activate


(defun appt-activate (&optional arg)
  "Toggle checking of appointments.
With optional numeric argument ARG, turn appointment checking on if
ARG is positive, otherwise off."
  (interactive "P")
  (let ((appt-active appt-timer))
    (setq appt-active (if arg (> (prefix-numeric-value arg) 0)
                        (not appt-active)))

In some areas of mathematical usage, zero is both positive and negative.
Sometimes for computational purposes, it may be necessary to consider
signed zeros, that is, treating +0 and −0 as two different numbers. 

Would it be possible to clarify this in the defun description string,
saying: 

ARG is positive (ARG > 0), otherwise off.
