1) I think your best bet would be to look at the documentation for the
module whose object $dbh is. What the method returns should be in there.
2) Look at eval. You should be able to read in the text and use eval{} to
interpolate your variables.

Subject: variable behaviour question and including files
1){ If say something like:
my $profile = $dbh->selectrow_hashref("SELECT * FROM users WHERE
username = '$username' AND password = '$password'");
and the SQL query doesn't return anything, will $profile be defined or
undefined?
}
2){ I want to keep large chunks of html outsite my main scripts but so
they can be accessed, and brought in just to print to STDOUT. I have
tried keeping them in individual html files then doing
while (<HTMLFILE>)
print;
}
but I also need parts of the html to be perl scalars relying on values
from the main script. Is this possible? You see I want to keep my main
script as free of html as possible for portability's sake.
cheers
