You may want to begin with the TROLL programming language:
http://www.intex.com/troll/program.html
Once you have mastered that, you could get a job with Trolltech

Can't be a very good language there's no download page for me to get

Well considering the fact that you haven't posted to Usenet
before ( according to google ), your IQ can't be that badly fried.
While many of the jobs that require programming do require
a high IQ I've met many a programmer whose low IQ does not
deter them.
Good luck.

I'm not so sure. Did you notice his use of English?
Hardly a sentence without a spelling error!
There's unlikely ever to be a compiler capable

Brian,
No one is stupid in this world! It is only stupid if you think you
are. Learn Ada and you will never regret it. It is not difficult to
learn but only time that's matter.
I have many colleagues in my work place have not even got into
college. But their interest in computer and perseverence make them
software engineer today. They use Ada in their daily programming
chores.
Get a book teaching Ada for a start and you will find Ada is very
different from others.
Go ahead. You can make it!

I don't know that I quite agree with that. Prolog isn't the same
conceptually as assembly language. Neither is a pure functional
programming language. Or maybe it is true if you think of Prolog
as having an implicit "tell me whether this is true" instruction
and pure functional languages as having an implicit "tell me the
value of this" instruction. But that's kind of a stretch.
Anyway, if the original poster is looking for a programming language

Subject: Dynamically Assigning Scalars On The Fly
Message-Id: <WoHF7.2919$Yk5.507617@news1.cableinet.net>
I have a 2 line csv file, displayed below as follows :
first,last,country
Mike,Mackay,England
What I want my perl script to do is take the top line, and change each one
of the field names into a scalar to reference it's value, for example my
script would now have the following scalars : $first, $last, & $country.
I would then have a print statement in my script just like the following :
print "$first $last, comes from $country";
and it should output : "Mike Mackay, comes from England".
However I want this script to create the scalars and assign the data
automatically for any csv file with any amount of fields without me having
to open up the script and manually enter the scalar names. Can anyone offer
any help of how I should go about : a) creating the scalars on the fly, and
b) assigning a value to that scalar.
I know how to open the script and get the top line only etc. It's just this
dynamically assigned scalars that I can't figure out. If you need a further
explanation then I can provide more info. Thanks for any advice/help.
Regards,
Mike Mackay.

Indirectly, the \n will be expanded to CRLF, though not the way you're
thinking.
The CGI specifications require that when the httpd is recieving headers
from a CGI program, it use your system's newline sequence [whatever that
may be] as the delimiter to tell what a line is, and when the httpd
constructs the outgoing headers, it always uses a proper CRLF to delimit
them, even if CRLF isn't the system's newline.
So the problem becomes getting your CGI headers to have "proper"
newlines between them... is "\n" right for this? Yes.
Perl will, if STDOUT doesn't have binmode set on it, translate \n chars
into the system's newline characters [if necessary. On unix and mac,
the \n already is the system newline character, so it doesn't need to be
changed on output. On win, \n [within perl] means chr(10), and upon
output in ascii mode, any chr(10) gets translated into chr(13).chr(10),
which is the system's newline sequence]

The regex suffers from leaning-toothpick-syndrome. Use a different
quote character. Also, you should anchor the regex... otherwise,
someone might have a referer of www.domain1.com.foo.bar.org, and you
would consider it valid.
#! /usr/bin/perl -wT
print "text/html\n\n";
unless( $ENV{HTTP_REFERER} =~ m[^http://www\.domain[1-4]\.com($|/)] ) {
print "Error.\n<br><br>\n";
print "This script cannot be run from this domain.\n";
exit;
}
I feel that I should also mention that many browsers don't send a
referer header, so this kind of code may annoy legitimate users, and it
will do very little to stop illegitimate users, since the referer header
is trivial to fake.

Subject: regex help please
Message-Id: <nteeuts03n2u09v1kb0t8plo2sglprrqfc@4ax.com>
I was given an Access database which I am trying to get into MySQL, I
read through the documentation on mysqlimport and it said that it was
only capable of importing text files. So I export my Access DB into a
pipe delimited file, pipes delimiting the fields, and newlines
delimiting the records. Well, to make a long story short, M$ Access's
Export feature sucks, many of my rows were divided on whitespaces
which resulted single lines looking like the following
3884|MC1|GW|Graphworks/Mirandas Needle|kit
|Mice Skating|EACH|$1.50|$0.75|MC1.JPG
My question is, how do I remove the newline '\n' on a line if the next
line doesn't start with a 3-5 digit number and then print that new
complete line to a seperate file?
This is what I have so far, and it doesn't work.
open (PROD,"<products.txt");
open (OUT,">out.txt");
@array = <PROD>;
foreach $line (@array){
unless ($line =~/JPG?/){ chomp; }
print OUT "$line"; }
any help would be appreciated.

I suggest that you don't. Instead, write a Perl program
that connects to both databases (using DBI, DBD-mysql, and
DBD-ODBC), does a "select * from foo" for each Access
table, and then inserts the results into the mysql tables.
Or if you can't do that (which you should be able to), have Perl
extract everything from the database and then use something like
Data::Dumper to spit it into a file format that Perl can handle. Then
transfer that, suck it back in, and spit it into the target database.
Or use one of those programs that's specifically designed
to transfer tables between different databases.

This indeed should not be done. Since using mutt as email-client, I
dislike any mails containing just an attachement. I have to press 'v'
first, then <RETURN>. After that, w3m is opened to render the page on
the console (which - since it is console - is sort of identical to a
text/plain mail). Then 'q', 'y' to confirm quitting, afterwards <any
key> and finally one of the arrow-keys to get back into mutt's inbox
view. This is a clear violation against longstanding console-tradition
of having to touch as few keys as possible to do somethinf useful.
I'd therefore strongly prefer the idea of the script's author taking the
pain on him to change a text/plain script to multipart/alternative
rather than doing the above odysee across my keyboard. ;-)

I find it's much easier to just type "d", as in "delete".

But no! You might just delete a HTMLized love-confession of a pleasant

Also, I would like to use the simplest Perl module (self contained).
Thanks a bunch in advance.

I appreciate your point of view. Though I can understand that you may feel
that it doesn't make much sense, it turns out it is helpful to Middle School kids
as a way of bridging from what they already know after 5 years of language arts
to what is present in programming languages. You will note that the Perl terms
of variable, block, etc. are introduced very quickly thereafter and subsequent
discussion is done in terms of those terms.
It also relates it to what else is being taught in the curriculum--not only
in language arts--but in introductory foreign languages.
--D.
You will note that the Perl terms are introduced shortly thereafter.

Good point. Originally, the schools were using Macs (I think this was 1998) where
the Perl brings with it its own IDE. After the schools switched to WNT,
I went with a straight-forward use of Notepad as an editor and launching the
programs via a double click on the files created. I did not know of an IDE
for WNT in 1999 when the sessions were first run. There were also
security concerns that I had to overcome so keeping things to a
minmalist approach was important.

I thought your approach made a lot of sense- it reminded me
immediately of my middle school age sentence diagrams, since
that's the only time in my life that they actually mattered :)
I also thought the approach of modifying a prewritten program was
a very good idea. The more real Perl code they are working with,
the more successful your course is bound to be.
Now some criticisms:
1) Maybe you could make better use of space; in places it looked to me
like the comments were detracting from the program flow. Try adding
some newlines or moving some comments to the right side of a
statement would look better. Or have the students fill in some
of the comments themselves, like
$A = <STDIN>; # what does this do? __________________________________
2) Adding a shebang line like
#!/usr/bin/perl -w
use diagnostics;
at the top of each program would be nice, even if you don't bother
to explain what it does. Also, I don't think it would hurt to quickly
wean them off the "single thing" language and call them "scalars".
That's how a math teacher would use the term, so you're killing two
birds with one stone :)
3) No variable declarations using "my", no "use strict"
I'm not sure if this criticism is really appropriate for middle
school aged programmers, but it's a very good habit. It might
be nice to introduce them at some later point in the course.
Lastly, one suggestion: some "find the bug" exercises might also
be useful. Give a description of what the program is supposed to
do, and let them figure out what went wrong; use Perl's diagnostic
messages for hints. Include things like syntax errors, precedence
errors, off-by-one errors, "= when you meant ==" errors, and
misapplication of deMoivre's rule (hmm, that one rings a bell :).
Good luck.
