Yes! There are two methods for multiple counters:
Copy the script for each page:
textcounter_home.pl -> home_count.txt
textcounter_about.pl -> about_count.txt
Use one script with a page parameter:
<!--#exec cgi="/cgi-bin/textcounter.pl?page=home"-->
<!--#exec cgi="/cgi-bin/textcounter.pl?page=about"-->
The script then creates separate count files for each page.
