Once upon a time, 16-May-01 04:48:11, Javier de las Rivas spoke thus about
'[D5] CDDAscript.dopus 1st version':

None of mine are bulletproof - why should yours be any different :^)

What the hell - this list is running a bit slow anyway ;^)

After opening a message port, (called myhandler - see earlier in script), and
assigning it to our lister, we wait at this statement until a message packet
comes along.
> packet = getpkt(myhandler)
We assign the contents of message to a variable.
> if packet ~= '00000000'x then do
If the message packet wasn't empty we process the following lines:
> event = getarg(packet,0)
> fname = getarg(packet,2)
> arg3 = getarg(packet,3)
We extract the arguments we require from within the message packet, (the
arguments sent depend upon the event - look in the DOpus5 ARexx guide for a
list of both).
Which we then process using a simple SELECT branch.
