Ok on win 98 with ActiveState perl 5.004 while working from the MS-DOS
prompt window I am running a program called rev.pl (code at end of
question).
at the ms-dos prompt I type:
perl rev.pl
a
b
c
d
ctrl z (note this doesn't echo it stops the input and begins the output
similar to ctrl d in unix?)
on the same line that ctrl z is typed in my msdos window I get the "b"
followed by et al...
b
c
d
---
a
b
c
d
---
where as the file output.txt shows.
a
b
c
d
---
a
b
c
d
---
Two questions:
1 Why the shift to the left in the first value "a" of the array?
2 Why doesn't the first value of the array show up in my MS-DOS window?
tia,
jb

You can see the code below.

#!/usr/bin/perl
# NAME rev.pl

my (@str);
open (OP, ">>output.txt");
@str = <>;
print OP "@str ---\n";
print "@str---\n";
print OP "@str ---\n";
print "@str---\n";
close OP;
exec 'notepad.exe', "output.txt";

Netscape downloads the image because it doesn't know what type it is.
But Internet Explorer fails to do that and hangs :(((
Is there a special Content-type to use to make Internet Explorer

Um, how about 'image'? :) Specifically, 'image/gif', 'image/jpeg', and so
forth.
: By doing :
: --
: my $logo = './logo.gif';
Note that the current working directory (.) is not defined by the CGI
spec. So using relative paths is perilous; it may work on one server, and
then fail miserably on another. And yes, this stinks...it's one of my
least favorite things about CGI programming.
: print "Content-type: foobar/gif\n\n";
: open (IMAGE,$logo) or die $!;
You might wish to try the open before sending the header, and send a text
or html response if the open fails. This increases the odds that
something useful will appear, on some browsers, in some circumstances,
maybe. :)
: print while (<IMAGE>);
Not a good idea. The image is a binary file, which may include e.g.
internal eof markers on Windows systems, The 'while (<>)' image is meant
for text files. Use read() instead.

Hey Craig,
Thank you for your reply!
Unfortunately it didn't help too much because what I wanted to do
DOWNLOAD an image, not VIEW it! Precisely I wanted the browser to
prompt the user to download it.
But happily for me I found the answer in the CGI-Authoring group, which
my question really belonged to.
So if anyone cares, here is the working (crossbrowser) code :
--
my $logo = "logo.gif";
open (IMAGE,$logo) or die $!;
print "Content-type: application/download\n";
print "Content-Disposition: attachment; filename=logo.gif\n\n";
binmode(IMAGE);
print <IMAGE>;
close (IMAGE);
--
/Makau.
PS : I didn't use your suggested read() function since I don't know how
to use it. Also it seems impossible to use "die" to send and html error
message (the directive 'or die "Content-type:
text/html\n\n<HTML><BODY>Error</BODY></HTML>"' can't seem to work)

You can't force a browser to do something from the
server-side. If the client side wants to `view' an
image/gif stream then it will, likewise if it wants to
`download' it, it will, no matter what you send.

If you have exclusive use of the CGI module you can set those variables
within the module itself. Otherwise, you can cludge it by using the
variable name twice.

Could you show some small code that demonstrates this
behaviour? The following works fine for me:
#!/usr/bin/perl -w
use strict;
use CGI qw(:standard);
$CGI::POST_MAX=1024 * 1000; # max 1M posts
$CGI::DISABLE_UPLOADS = 1; # no uploads
print header(); # for example
$ perl -cwT <this-script>
<this-script> syntax OK
$ ./<this-script> =
(offline mode: enter name=value pairs on standard input)
Content-Type: text/html
$ perl -v
...
This is perl, v5.6.0 built for i586-linux
...
[I get the same behaviour with 5.004 on another machine]

To stop the compiler warnings (-w) you could, as previously
suggested, use the variables twice (wastefull, I think) or
you could enclose these in a block and then turn off warnings
for that block by setting the special variable $^W to 0.
If you do that, make sure you use the 'local' directive so you
don't change the main $^W.

Yeah, it works for me too. I seem to remember having had problems with
this in the past though so perhaps it depends on the version of CGI.pm.
Mine is 2.56 with activePerl build 522 on win98.

There was also a thread here about this some time around the New Year,

You mean the *length* of a string?
$ perldoc -q length
The answer may not surprise you.
Or do you want to count _specific_ occurrences of chars
within a string?

By supplying the correct MIME encoded message to sendmail I would imagine
however what that encoding might be is something you will want to take
up with the RFCs that describe MIME or in a Newsgroup in comp.mail.* that
discusses these matters.
I would recommend that you use the module MIME::Lite and ask us to help
you overcome the problems you have with using modules instead.

First, do you have a directory called "Perl". I don't know what the
directory would be called with the latest build of Perl, but for Build 522
the perl interpreter and all the modules are in a directory called Perl.
If you have this, then you have installed Perl.
In reference to using Perl from DOS - yes, you run it from DOS. You may
want to take the time and read the documentation provided from ActiveState
and from the Perl Home page (http://www.perl.com/).
Do not be insulted by the following example. It may be simple for you,
but may benefit others in a similar situation.
To start you out:
1) open a DOS prompt
2) type "edit"
3) type in the following:
#!c:\perl\bin\perl
print "Hello World\n";
4) save the file as hello.pl in a directory of your choice
5) change directory to the directory with hello.pl
("cd <insert directory name here>")
6) type "c:\perl\bin\perl hello.pl"
The desired output should be:
Hello World

You can use the module DNS::ZoneFile to get the 'A' records from a zonefile
and Net::Ping to see if the host is 'alive'. About ten lines of code if
you use those modules I would say.

Well get hold of a more recent one then. Its free. It'll compile out
of the tarball on Linux and once you've used it you'll never want to
touch MS Word again <huh ?>

Then use the module CGI.pm to get the parameters. If you can get your
head round what it says in the manual then you'll be fine. CGI.pm has
been distributed with perl since 5.00404 you are bound to have it.
Try :
man CGI
Or
perldoc CGI
For starters.
You could do this in about ten lines of code and everything is explained
in the documentation for the above module.
If you have more general questions about CGI as a whole you will be better
off asking in comp.infosystems.www.authoring.cgi .
