Fixed-time timers problem-help!

Hi Bryan,

I have written some general purpose handlers for sending messages. They 
make sure that the message is not sent multiple times and the 
"sendMessageAt" handler allows you to specify a time rather than a 
delay for the next message. They may not be exactly what you want, but 
they may give you enough of a start to do your own thing. As usual with 
emailed scripts, beware of wrapped lines that shouldn't be wrapped.


-- send message at a specified time
-- use 24 hour time, so next available will be used
--  sendMessageAt "showClock", "fld ID 1026 of cd 1", "11:10"
on sendMessageAt handlerName, where, atTime
   put the seconds into timeNow
   put timeNow into eventTime
   convert eventTime to dateItems
   set the itemDel to ":"
   put round(item 1 of atTime) into atHour
   put round(item 2 of atTime) into atMin
   set the itemDel to comma
   if atHour > item 4 of eventTime or (atHour = item 4 of eventTime and 
atMin > item 4 of eventTime) then
     add 1 to item 3 of eventTime
   end if
   put atHour into item 4 of eventTime
   put atMin into item 5 of eventTime
   put 0 into item 6 of eventTime  -- adjust to even minute
   convert eventTime to seconds
   put eventTime - timeNow into theDiff

   setupNextCall handlerName, where, theDiff
end sendMessageAt

-- send a message in a specified number of seconds
-- clears any pending instances first
-- setupNextCall "showClock", "fld ID 1026 of cd 1", 60 - theSecs
on setUpNextCall handlerName, where, inSeconds
   put the pendingMessages into pMess
   repeat for each line p in pMess
     if item 3 of p contains handlerName then cancel item 1 of p
   end repeat
   if there is not a where then exit setupNextCall

   if inSeconds < 1 then
     do "send " & quote & handlerName & quote & " to " & where & " in " 
& inSeconds*1000 & " milliseconds"
     do "send " & quote & handlerName & quote & " to " & where & " in " 
& inSeconds & " seconds"
   end if
end setUpNextCall
