Okay, the EOF comes from these statements:
print <<"EOF";
html blablahblaah
EOF
This means print all text from the print statement until the text matchs
"EOF"
If you are seeing EOF in the html, you need to be sure that the print
statement is in place referencing the EOF. If it is, run the script with
/path/to/perl -w /path/to/script.pl or /path/to/perl -d /path/to/script.pl
If you need to set variables, setenv QUERY_STRING
<variable>=<value>\&<variable>=<value>\&<etc>
That may not work if you are not using tcsh or csh as your shell. I forget
how to set environmental variables in bash.
