I /think/, under Perl, "\n" is the system newline, regardless of the OS.
Under Windows, it would still be "99\n"

What is the origin of $line ?
if you wrote $line = you should remove the "\n" and or "\r\n" at
the end of $line.
And if the user enter not numeric value you should always shuch an error.
You should check if the value is numeric or use 'eq' instead of '!=' .
If you removed the "\n" ou "\r\n"

I'd guess $line is never set before the first time it is compared to 99.
Either (1) change line 11 to:
$line = 0;
while ( $line != 99){
or (2) use a do-while loop.
do {
...
} while ( $line != 99);
