You should post more of you code to let us see what is happening but on your system you should write to a file as so:

use CGI qw(:cgi);
use CGI::Carp qw(fatalsToBrowser);

open(FILE, ">>nm.log") or die("$!");
print FILE "log info here\n";
close(FILE);

With using the CGI.pm you allow yourself easy error checking. Now if the script cannot open the file it will come back with an error saying it could not open it.

As for your shebang you should put something like: #!c:\path\to\perl
NT systems sometimes ignore this and I am not sure what type of server that is run on NT systems that does but it is good practice to add the shebang any way.

Hope this helps,

Stanley

Re: open file [In reply to] Can't Post
The problem was due to the fact that if you copy the following text from this forum, you will get a | followed by a space followed by a |, not a | followed by a |:

<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>


open(FOO, ">bar") &#0124; &#0124; die;
</pre><HR></BLOCKQUOTE>

And to Perl, that ends up being a syntax error. UBB folk -- any idea as to why &#0124; &#0124; gets a space inserted in it?

Hi

for a header on a nt you dont put the c: in header

example::

I have win95 and i installed apache and perl on my computer.. so the header would be

#!/apache/bin/perl

you dont put the c:/ in a header.
