[ale] source code

[Terry Bailey]

I see that it was confusing as to what I meant by source code.  I 
meant the html code generated by the cgi Perl script that is sent to 
the client browser.

Thank you for your thoughtful answer.

At one time I was involved with complied Perl and wondered the other 
day if that was still being done.
