open(data,' variable problem

[NoViagraHere]

I am trying to open a text file in the same directory as the script is
located to retrieve stored info. The text file is simply named:
216.1.1.2


This code will NOT work:

$ip = '216.1.1.2';
open (data, $ip);
@mailtext=<data>;
close data;
print @mailtext;


however if I replace $ip as below, It DOES work. Any ideas?

open (data, '216.1.1.2');
@mailtext=<data>;
close data;
print @mailtext;

It works both ways on a Linux system using perl 5.8.1.

I'd say try making it look like "open (data, '$ip');" or "open (data,
"$ip");" I doubt it'll work, but it's worth a shot

You don't say why it is not working. You should be checking if the open
succeeded:

open( data, $ip ) or die("Can't open $ip: $!");
