Ah this suffices as a quick hack. But what if I have package x in repository
a and package y in repository b. No matter which repository I choose, there
will be packages that won't be upgraded. Needless to say, I have a few such
packages that are not found at Active State's, for example.
hard to notice that more input is requested from me. <snip>

You can have it beep by having it print an ASCII BEL character at the
appropriate places.
That is what I was thinking, too. THe easiest representation is "\a" for
alert bell I believe.
write a wrapper script for ppm that notices when a package choice is
presented
That will do fine for my basic needs, thanks for the idea. Now the problem
is how do I wrap PPM so that I can both read from and write to it?
And how can I tell, without dead locking the whole program, that PPm has no
more output to offer until I press enter? I know these are very common
questions but please bear with me for a while.
I know about the system function as well as using pipes for the open
function but neither will do for asynchronous I/O. The Perl FAQ talks about
the package called IPC::Open2 but not knowing Unix, the manual is total
Greek to me (maybe it could be improved some day). I've also had a look at
the perlipc HTMl file but again I don't seem to be getting that much out of
it, frankly speaking.
I'd liek to see a bear bones example of async input and output that will
certainly work on Win32. Could anyone come up with such a script and go it
through with me, or point me to a more detailed and less Unix-centric
explanation of the open2 and 3 functions?
Mind you having a DOS and Windows power user background, even STDERR seems
like a Unix:ish concept to me as it is poorly supported in DOS. I believe XP
has some quirky command extensions to redirect STDERR but they are not
commonly known. THis whole STDERR affair is OT in this thread, it mainly
serves to give an idea of how little Unix I know apart from some basic
commands, <sigh>. And even so The ancient SunOs running at the Uni machine
is far from anything I would call user-friendly. Oddly enough, I find Perl
much easier than most Unix commands. But I'll stop right here before this
whole thing is totally OT.
