I don't see why you should write your pager as '| more' will work both on unices and windoze...

But, If you want to do it anyway, a simple test in front of each print :

 if(++$line > $LINEMAX) {
     $line=0;
     getc;
}

should be enough for simple/small scripts...
Or to be a little bit cleaner, using print2 instead of print, whith print2 defined like this :

sub print2 {
 if(++$line > $LINEMAX) {
     $line=0;
     getc;
 }
 print @_;
}

UPDATE :
Term::ReadKey May be more appropriate than getc.
Anyway you got the idea...
UPDATE2 :
This answer is for oaklander, I replied to the wrong post. Apologizes (especially to Hotshot).

• 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.
