Folks,
This may be a naive query, but dashed if I know it.
I have a large dataset, of financial data, and I need to check the
results of some trading strategies on it. I have read the data into a
hash of hashes of hashes, as I believe it's better than read this into
an array (Or
What does $ stand for in the following statement?
print$_\t, * x $n, \n;
$_ is the default input and pattern-searching space.

DESCRIPTION
You might want to try out the Date::Manip package. It has a function
Date_Cmp which compares any two dates. You first read the date through the
function ParseDate in the module, and then compare the dates through
Date_Cmp.

Dear Allison,
Does anyone know how to write to an Excel document? I've opened the
document using OLE but I cannot find any documentation on how to store data
in the spreadsheet. If anyone knows what the commands are to do this please
let me know. Thanks,
Try the
This might seem trivial, but it has me stumped.
The variance of numbers 0..20 is 38.5.
Then why does Math:NumberCruncher show it as 36.6667?
Here's a sample prog, and it's output. Here test04.dat is a file that has
numbers 0 to 20, on separate lines.

Hey all,
$card_no = 1234567901234567 # 16 digit number
How would I go about splitting that number into an array?
Folks,
Consider this code snippet:
Here $ParseFile is a plain-text file, which could be gzipped, bzipped, or
not compressed at all. I'd like my program to determine this, open the
file, and cat it to another program called discretise.
In the code below,
my(@PARSELIST) = @ARGV;
);
READ is the input pipe
ZIPIT is the output pipe
Perl Gurus, Yeah I should have used the ZIP module.. I am too lazy to change
it now.

hi Ron,
another unix command is flip.
i've written a small perl script that converts a dos file to a unix
one.
as you can see, i've just substituted the \r\n with a \n. the reverse
can easily be done. this is a working example. it's not fast, but
workable. i'd welcome
The command is
unlink $_path/* if -r $_path;
This will work.

Hi, I wanted to delete all files under a directory but not the directory
I tried this:
my ($_path) = c:/EventLogs/;
unlink $_path if -r $_path;
But it didn't delete teh files which are under the directory
You might want to check the permissions of those files.
The command works fine here.
But I guess the mistake is that you're working on Windows, and there you have
a back-slash ( \ ) instead of a slash ( / ).
Try this:
my ($_path) = c:\EventLogs;
unlink $_path/* if -r $_path;
This should
Are you giving the propoer syntax?
your command should've been:

Also, apropos to my earlier mail, can this be done using Date::Manip?
