Hi,
Perl2Exe is a command line utility for converting perl
scripts to executable files.This allows you to create
stand alone programs in perl that do not require the
perl interpreter. You can also ship the executable
file without having to ship your perl source code.
Perl2Exe can generate executa
on unix u can use perlcc.

could you please mail an example so that your query
become clearer.
do you have any criteria for distinguishing between
the bad and good ones. if yes, then use that to get
the "bad elements" from href .
well your example can make the question clearer.
On Linux , open /etc/smb.conf and set the attributes
there. It is basically for setting the attributes for
printers etc. But every thing is file on linux so you
can do it.

Number is say XY then u can write it as 10X+Y.
Now you are doing 10X+Y - (10Y+X)
which is 9(X-Y) where X and Y lie between 0 and 9 . when X >Y you get multiples of 9

This will not work as it will also forbid creating new files(according to the question
only sub-DIRS r not allowed) in that directory. There is no Unix-provided solution for
this. One can write a function, which can be called first in any perl code (related to
some task in that path) to ensure
yeah u r right.

The file generated by 'perlcc' does the same task as the perl file. In the program
where you are requesting the service, change the name from perl file(which was earlier
to 'perlcc') to the generated binary file.

Hi ,
The name of the global var is put into symtab during compilation while that of local
var is converted to its offset. So if u want to "NAME" a var at run-time, u won't
succeed. All u can do is that use hash-table with the KEYNAMES as those words
appearing in the file.

the keys are the domain part of the e-mail addresses.
the value part is the reference to an array of id part of the e-mail address.
instead of reading data into ur GOOD and BAD fd's , read t

go to the point where u want to insert the word. read the file from that point to EOF

use system('users') on unix systems to get the name of all users currently logged on

hi,
use of BEGIN is better because it is called by perl-run-time before ur program gets
executed and if u have a large chunk of variables to be initialized in this way, it is
the best way.

hi,
You may declare my variables at the outermost scope of a file to hide any such
