(a) You haven't declared or assigned $LINE, and
(b) You are trying to compare, rather than assign the next line in the while loop.

That makes Perl go into an infinite loop.

The correct method is either this (fetch next line and test for truthfulness) -

Code:
...
while (<MY_FILE>) {
...

or this (fetch next line, assign to $LINE and test for truthfulness) -

Code:
...
while ($LINE = <MY_FILE>) {

ASP-PERL(1p)						User Contributed Perl Documentation					      ASP-PERL(1p)

NAME
asp-perl - Apache::ASP CGI and command line script processor SYNOPSIS
asp-perl [-hsdb] [-f asp.conf] [-o directory] file1 @arguments file2 @arguments ... -h Help you are getting now! -f Specify an alternate configuration file other than ./asp.conf -s Setup $Session and $Application state for script. -d Set to debug code upon errors. -b Only return body of document, no headers. -o Output directory, writes to files there instead of STDOUT -p GlobalPackage config, what perl package are the scripts compiled in. DESCRIPTION
This program will run Apache::ASP scripts from the command line. Each file that is specified will be run, and the $Request->QueryString() and $Request->Form() data will be initialized by the @arguments following the script file name. The @arguments will be written as space separated words, and will be initialized as an associate array where %arguments = @arguments. As an example: asp-perl file.asp key1 value1 key2 value2 would be similar to calling the file.asp in a web environment like /file.asp?key1=value1&key2=value2 The asp.conf script will be read from the current directory for parameters that would be set with PerlSetVar normally under mod_perl. For more information on how to configure the asp.conf file, please see < http://www.apache-asp.org/cgi.html > SEE ALSO
