Check your closing quotes - the line as it is above won't compile. You should have: print "\n"; This may or may not be your problem.

Just that up to the run-time stuff. Otherwise I can't guess why it's behaving this way. Cheers, Rob -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

thanks.

In that case you will need to decide what the "structure" is, and what
you can guarantee. A normal text database is going to be parsed in the
following general manner:
open the file, step through the delimited portions of the file, in many
cases line by line with a while loop, until some condition is met, in
many cases EOF, possibly split on some character(s) within each
delimited portion, and store those to some data structure that can then
be manipulated or fire off events that handle things such as a start of
a new element, the body of an element, the end of an element, etc.
perldoc -f open
perldoc perlopentut
perldoc -f split
perldoc -f close
For instance a comma delimited file could be handled like so (though
some would prefer DBD::CSV)...
my $file = '/path/to/file.csv';
my $INPUTFILE;
open($INPUTFILE,"$file") or die "Can't open input file for reading: $!";
while (my $line = <$INPUTFILE>) {
my @values = split(/,/,$line);
my $count = 0;
foreach my $val (@values) {
print "Element $count: $val\n";
$count++;
}
}
close($INPUTFILE);

Re: write a parser using perl
You'll want to look at:
perldoc -f pack
perldoc -f unpack
if you're working with fields of pre-determined lengths and the database
files aren't delimited. Perhaps if you could post an example we could
give you better advice.

Re: changing backgorund color error
Not to be too much of a pain but... You should reconsider using the bgcolor property at all since it has been depreciated. Consider using CSS like:
body {background-color: #004152; }
... Or at least: From the looks of your code, I'm wondering if you 'use strict'. If you aren't, start. Also consider how your variables are scoped. It looks like you're causing yourself all sorts of headaches by not limiting the visibility of your variables. You'd also avoid tons of quote errors and improve the readability of your code by using the << operator like so: print < Content-type: text/html Results of Search
body {
background-color: #004152;
}
Results of Search in $title Below are the results of your Search in no particular order: END_OF_HTML for my $key (keys %include) { next unless $include{$key} eq 'yes'; print qq($titles{$key}\n); } print < Search Information: Terms: END_OF_HTML print join(', ',@terms), "\n" print < Boolean Used: $FORM{'boolean'} Case $FORM{'case'}\n"; Back to Search Page $title; END_OF_HTML } The below given part of code from a cgi script is working fine but when I try to change the back ground color to print "\n"; print "\n"; looks like you need to maybe this will help..you have that qoute at the end..by the 2 print "\n"; -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: changing backgorund color error
Hi Jonathan,
I'm going to take issue with you on a couple points. I think all the original poster
needed was to take a second look at his quote escaping.

Depends on why it has been deprecated. It works. It's very backwards compatible. It
is much more portable than style specifications.

Great advice.

Depends on the visual effect you want. I have particular standards for readability in
both HYML and structured programming, and they are not the same. Therefore I prefer
to use:
indent (int spacing, string test) {...}
to set the specifications for how my output will appear, while maintaining the flow of
indentaion within my program code. It is a matter of taste.

Quite true. You have to even drag out the font tags for compatability
reasons at times, but last I checked, the only place I needed to abandon
XHTML and CSS was for the mac's default mail program... I forget its
name but it has no CSS support at all. All the same, I was troubled by
the missing and tags as indicative of a more general malaise
in regards to the evolving standards...

Also true, it is a matter of taste. My main point in throwing it out
was to make sure it was something people were aware of. In general,
quoting HTML can be a pain without a few perlish tricks like << and
qq(). These days I'm a fan of slurping an XHTML template up into a DOM
with XML::DOM::Parser and working with it that way. Its all about taste
and fads, that's why programming is an art form... at least with perl.
