Indeed. One does start with the manual. How does one get the manual?
"man perl" [1]. What does the manual start off with? A list of more
manuals! What's high in that list - the second page of "man perl"?
Right. A pointer to the Perl FAQ.
You can't expect everyone to know everything. But you *can* expect people
to look at the documentation they are given.
[1] Or whatever is the equivalent on inferiour systems.

No, if they are Unix savy, they try "man perl", and guess what? On the

A unixsavy person will type "man perl" which nicely lists all the other
man pages. inclusing perlfaq. A unixsavy person knows what:
"For ease of access, the Perl manual has been split up into several sections."
followed by a list of man page names means.

Who greps manpages for "doc"? The manpage is the documentation. You
read it, and in the case of perl read the other pages it tells you
about.

If the newbie is an idiot, and uses grep not to search and then check the
context, but to read.
A newbie needs to learn how to read documentation on their system before
they learn how to use perl.

perldoc is irrelevant, man works just fine and provides access to the
same documentation. Arguably better access due to the wonders of
man -k/apropos.
If someone uses unix and does not know about man, then they should stop
and learn about it *before* doing anything else with unix. Unix is
unusable without it.

How does that random text lead to trying a "help" command. I see no
reference to such a command. How does it lead to "help perl" more than
it leads to "oodles perl" or "mail perl"?

Again, perldoc is irrelevant. man works just fine. It is not the job of
the perl documentation to explain the use of man, that is the job of
"man man" :)
Do you want the perl documentation to include tutorial information on the
use of man, the use of the various microsoft help systems, the use of
a web browser to view HTMLized docs, etc, etc.
Assumming the reader can read documentation on the system they are using
is reasonable. How did they know to how to run perl otherwise? How did they
know how to create a file?
You could always of course upgrade to the current stable version of perl
which does in fact provide a reference to perldoc findable by your strange
"grep the man page for doc" approach to reading manpages:
; man perl | grep doc
Reformatting perl(1), please wait...
gate the rest of Perl's extensive documentation.
perltoc Perl documentation table of contents
perlpod Perl plain old documentation
perlpodspec Perl plain old documentation format specification
perldoc Look up Perl documentation in Pod format

It isn't buried.

So what, perldoc isn't important. It provides a nice way of specifying
perl documentation in this newsgroup, saying "perldoc perldata" is
nice since "man perldata" is meaningless on windows.
perldoc is nice for searching the FAQ (though not as nice as grep), but
you aren't meant to search the FAQ at the beginning, you are meant to
*read* it.

But that isn't a FAQ. Maybe schools in your part of the world are different
than over here. But over here I've never seen something that resembles a FAQ,
something with a list of questions which are have actually been asked
frequently (or even just once) with answers.
Things like:
* Which teacher is most likely to let me leave early?
* Which areas are best avoided if I don't wish to get in a fight at lunch?
* Which toilets are the cleanest?
* On which day are the weekly staff meetings that make it easy to sneak out
at lunch?
* Which computer in the library is fastest?
* How late can I be for roll call?

Actually I don't see those posts either. I think since so many people
seem to have a problem seeing it, could it be something with Tad's
server not properly propagating posts? Why assume it's someone's else
when it is possible the problem can be at the source. Other then his
posts my server seems to show anything that google shows (and then
some.) Just Tad's posts don't always appear.

I got a FAQ (it wasn't called that; the term had not yet been invented)
when I started college. It didn't have such trivia as the above, but it
did have the answers to such questions as:
* What are good local radio stations?
* What are good local restaurants?
* Where are you allowed to park on campus?
* Who are useful administration personnel to know?
* What resources are available to you as a student?
etc.

And shouldn't it be either:
if ( m// )
or

A context-free grammar for this would be:
S -> a S u | u S a | c S g | g S c | [nothing]
You *could* do this with Perl regexes, but it's unweildy (and inefficient,
I can assure you):
my $pair;
$pair = qr{
a (??{ $pair }) u |
u (??{ $pair }) a |
c (??{ $pair }) g |
g (??{ $pair }) c |
(?# nothing )
}x;
if ("acgu" =~ /^($pair)$/) {
print "matched '$1'\n";
}
However, it's probably easier just to match a sequence, and then try to
match its reverse:
if ("acgu" =~ /^(([acgu]+)(??{ complement($2) }))$/) {
print "matched '$1' ('$2')\n";
}
sub complement {
my $str = reverse shift;
$str =~ tr/aucg/uagc/;
return $str;
}
I didn't need to use "use re 'eval'" for either of these, by the way,
because the variables in the regexes are qr// objects.

Actually I did after you posted...just to be sure since it had been a
while since I did this...
And of course it didn't work...I guess my fallback is that I'm a crappy
perl programmer...:)...I think I actually rewrote it too way back when...

Yep. That works brilliantly. Thanks.
And just to polish it further, to get the substring start site, it
should be:
if ($string =~ m/(?=($substring|@{[revComp($substring)]}))/ig) {...}
Good thing I started lurking this newsgroup again... :)
BTW...where is a reference for subroutine calls within a regex?

Step 1 is to recognize that it isn't the regexness that matters,
it is the double-quotishness that matters.
Step 2 is to lookup subroutine calls within a double-quotish string. :-)
perldoc -q expand
How do I expand function calls in a string?

If you're gzipping the output stream, then the removal of spaces isn't likely
to change your transmission size significantly, if at all. The compressor
will flatten them right out, without risking the content of the HTML.
Also note that if you have a CGI that sends back something besides HTML,
such as image or sound data, this will completely screw it up.
