- !Notify version 1.0
- written by Adam Curtin 1993 (adam@ifeng.demon.co.uk)
-
- Notify allows immediate communication between Econet stations.
-
- Versions of the NetFiler pre-RISC OS 3 had a "Notify" menu item which
- allowed you to send a short message to another station. The message appeared
- in an error box on the remote station, which blocked the whole machine until
- OK was clicked or Escape or return pressed. If you were in the middle of
- typing when a message arrived, the incoming notice box could eat a return
- and disappear before you'd had a chance to read it. It was all a bit naff.
-
- In RISC OS 3, the "Notify" item was quietly removed from the NetFiler menu
- to be replaced with ... nothing.
-
- There are, however, hooks in the wimp to enable third parties to write
- their own much more friendly inter-station communications utilities, and
- that's what !Notify is.
-
- It sports a number of wacky features:
-
- * Takes up no space on the desktop or icon bar, yet it's just a hot-key
- press away when you need it.
-
- * Pops its window open and to the front when a message arrives,
- ensuring you don't miss anything.
-
- * Optionally beeps announcing an incoming message in case eg the screen is
- blanked.
-
- * Accommodates *much* longer messages than the NetFiler notify, with
- each message presented on a single line in a horizontally-scrolling
- window.
-
- * Allows selection of the message destination from a menu of user names
- rather than net/station numbers. The menu is regenerated each time it is
- displayed to ensure it remains up-to-date. Your own login name is
- greyed out.
-
- * Optionally sets the destination station to match the sender of the last
- message to allow easy reply and prevent embarrassment!
-
- * Maintains a log of both incoming and outgoing messages, annotated with
- the source/destination station number (for incoming/outgoing messages)
- and distinguished by colour, making it easy to follow conversations and
- refer back to who said what. The latest message is highlighted in yet
- another colour.
-
- * scrolls the window to the bottom when a new message arrives, in case
- you're scrolled up the log somewhere.
-
- * Allows earlier incoming or outgoing messages to be recalled and edited
- for resubmission.
-
- * Log can be cleared in case it contains incriminating statements
-
- * Any other station's Notify log can be remotely cleared in case they
- contain incriminating statements!

- | How to use !Notify ... |
- +------------------------+
-
- But first: You need Econet of course, and you also need to be logged on. The
- program runs even without these, but it's not terribly useful!
- If you're really desperate to play with it, you can send messages to station
- 0.0 - the outgoing message appears in the log but is not sent out.
-
- After starting the program, the only indication that it's running is an
- entry in the task manager's "Application tasks" list, but the program is
- running, and you are able to receive messages from other stations.
-
- To send a message, first open the window using Ctrl-Tab. This *almost*
- always works, but a couple of applications consume Ctrl-Tab themselves. If
- one of these applications owns the caret, give the caret to another window.
-
- With the window open, click in the writable field right of the "Station:"
- label and type the destination network and station number, eg "0.42" If you
- omit the network number it defaults to 0. Alternatively, click menu over the
- message composition field and choose a user by name from the list.
-
- Then get the caret in the "Message:" box and type. To send the message,
- simply press return. The message box clears ready for the next message,
- and the outgoing message is added to the bottom of the log.
-
- To recall an earlier message, simply find it in the log and click on it.
- This copies it down to the message field exactly as if you'd typed it in.
- Alternatively, with the caret in the message field you can use the up and
- down cursor keys to cycle through the entries.
-
- +----------------------+
- | The !Notify menu ... |
- +----------------------+
-
- Clear ... clears the log. Alternatively, double-click in the log window.
- Beep ... Enables/disables the incoming message beep.
- Reply ... Enable/disables the automatic setting of the Station: field when a
- message arrives
- Quit ... Guess.
-
- Beep and Reply are both initially set. They can be turned off using
- command-line options, either in the !Notify.!RunImage file, or when starting
- !Notify eg from a !Boot file.
-
- The options are "-b" to turn the beep off and "-r" to turn reply address
- generation off, eg:
-
- (in the !Run file)
-
- Run <Notify$Dir>.!RunImage -r %*0
-
- (in a !Boot file)
-
- Filer_Run SCSI::Eidos.$.Adam.Apps.!Notify -t

- | Clearing a remote log |
- +-----------------------+
-
- Send a message consisting of the single character "`" will clear the log in
- the receiving station. There's no way of disabling this on the receiving
- end as I feel you should be able to insist that your comments are deleted.
- This makes it open to abuse but the novelty of clearing someone else's log
- soon wears off and does no real harm.
-
- On the other hand, an early version of !Notify allowed any command to be
- sent and remotely executed. This had some amusing uses, eg tidying the
- pinboard or setting the backdrop to an annoying sprite; some mischievous
- uses eg turning the ARM3 cache off or starting a dozen copies of !Paint; and
- some destructive uses ... you could easily wipe an entire hard disk,
- format a floppy or run a machine-crashing application.
-
- After successfully amusing and irritating some colleagues :-) the thought of
- releasing a program with such potential for evil was just too much. This
- version has all such code removed.
