I'm glad you like it. Looking forward to the next version.

It will run and render the ascii art. You might need to add a space
here and there, depending on your configuration.... I recommend
courier fonts for viewing. That renders best. Actually I am persuaded
most ascii art is rendered via the courier font... I'm sure there is a
good reason for it.

Dear Sir!
I'm a real beginner on Perl programming.
I use Active Perl(V.5.8.6) on Windows XP Home Edition.
And I want to use Image::Magick to create image.
On the dos prompt, I typed as follows
>ppm rep add threoryx http://theoryx5.uwinnipeg.ca/ppms/
>ppm install Image
Maybe no packages exist for Image::Magick
How can I use the module on Windows system?

I don't know, but I'm getting sick of the constant
"I'm so new" plead to get a question answered.
If your so new to Perl, shouldn't you start with
something simple like, what a variable is?
Maybe you should get the random phrase, Perl code
generator (check Cpan) and put in "Image::Magick"
seed, and test it. Works for some..

Doesn't seem to be one at the uwinnipeg site, but this should work:
ppm install http://www.bribes.org/perl/ppm/Image-Magick.ppd
Visit http://www.bribes.org/perl/ppmdir.html for a full list of what's
available there.
Cheers,
Rob

The CPAN documentation on perl threads state the overhead of creating
a thread is rather large. Anyone know why or could point me to a
website that explains the reason.

Less than a process. I can only imagine the win32 api on that
platform. Its all about state and context, as the threads
switch, the manager has to save the execution state of the
leaving thread, then install the newly running thread state.
State is all the things you don't want to know about.
Low level stuff like the adresses of the currently running
and newly running code address (IP) and things like where
data is, like the Stack and also the registers. So, it basically
takes an image of the state of the cpu registers and all of the
segment pointers relating to code path and data, then reinstates
the new one. Back and forth it goes. On windows I think theres
64k threads that state can be saved for.
You should take a course on assembly to fully understand
machine mechanics. Others will bullshit this out forever
just wait and see....

Is it true the port of fork() is faked by using threads? If so why?
I haven't been able to find a good explanation.

Hahahaha, fork() is a Unix word and it looks like a Perl word.
In windwos, you CreateProcess(), wheather you pass on handles
to the child, or you wait for termination is arbitrary, ie:
sync/asynch, doing other things and waiting for an end
signal (your event queue is signaled) or just wait.
There is no other options. No matter what Perl says it truly
is that simple. Funny thing in windows, the only IO that happens
is CreateFile(), ReadFile(), WriteFile(). Thats the extent of
windows IO et all !!! There is no other io in windows,
file io, drivers, services, anything. No matter what hack
wrappers do for you (ie:Perl and others) it distills to this.
I used to write NT 3.50/1 device drivers. I wrote alot of em.

Followup, fork() will create a new process on any platform.
"fork()" is a terrible acronymn. If you ever go beyond and
drill down you will find these are all macro's and not
language intrinsics. After 25 years at this, I can truly
tell you anybody says they know what "fork()" is, is a
goddamed liar!!
