Well, the first thing anyone will tell you is

use warnings;
use strict;
[download]

and see if Perl itself starts telling about anything odd or finding any mistakes.

I see that you invoke the program with a line containing << !. That changes STDIN to read from something else (I'm not familiar enough with ksh to know if ! has a special meaning or is the name of a file). That stays in effect through all the programs called down through system, so the use of STDIN won't prompt the user but will keep reading from ! (whatever that is).

What is the purpose of that? I don't see your main script reading anything from STDIN itself.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
