Just as a little background, I am working on a BioInformatics program that
runs on large (about 300 meg) text files. I am using a filehandle to open
and load it into an array. Then I use the join command to read the array
into a scalar variable in order to be in a workable form for my
computation
Hi there Wiggins,
Thank you for your advice, I have heard of Cygwin and tried to visit their
site but it says it can't find the domain. Will try later. I have also heard
of ActiveState. I am wanting to develop pure CGI programs with Perl (when i
finally learn it), is this setup still good for this

Hello,
When you write
$calc=3+5-2;
print $calc."\n";
you get 6. (number, not the string "3+5-2")
When you write
while () {
$calc=$_;
print $calc."\n";
last;
}
if you run that last one and type 3+5-2, you get 3+5-2.(string "3+5-2", not the number
6)
Why is it so? And how can I get it to
Aye. I once made a simple program, just for calculating + and *. I had no
problem with that. Which means somethin' like:
#!usr/bin/perl
print "Enter a number.";
$number = ;
# *ing by 2 (can't get to the right word)
$result = $number * 2;
print "Aye, the result is" . $result;
Which you could do

You have to compile the input. Try using eval.
It should look something like:
while () {
$calc= eval $_;
print $calc."\n";
last;
}
But, don't forget to catch errors.

Hi Jacques,
Well, this is about data types. Unfortunately, Perl tends to haze up the issue by
doing away with explicit types and doing everything implicitly. In a programming, as
opposed
And how can I get it to calculate the thing?
print eval($calc) ."\n";
Hi Jacques,
Sorry. In my previous post, I answered your first question, but offered no solution.

A slightly corrected version of my _CSV with commas in the fields_ solution:
sub DataPrint {
my($Handle, $key, $hashref) = @_;
my $Data = $$hashref{$key};
$Data =~ (s/,/%2C/g);
print $Handle "$Data,";
}

Anyone?
This file works on my computer but when I upload it to a unix system and
try it from the internet it gives me a 500 error. Can anyone tell me what
the problem is?? Still new at perl.
Hi,
I have a bookmark-file from opera6.11 that contains a lot of duplicate

I would like to be able to remove all duplicate entries without
destroying the structure of the file.

format that could be sent through 'uniq
