Is it possible to name a variable as the numeric value of a scalar?
Well, all scalar variables you create must start with a letter. But, if
you're talking about something like this:
$var = hello;
${$var} = 1;
print $hello;
You can do it.

But you shouldn't. Ever. And use strict rightfully keeps you from
doing so.

Escape Characters
I'm trying to send mail to users returned from a database. The problem occurs when sendmail sees the @ in the email address. Is there a function to escape reserved characters? Also, does sendmail allow sending as HTML? TIA bb -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

wrap your execute() inside an eval, then examine $@. see below:
HA:eval {
HA: $sth-execute('[EMAIL PROTECTED]');
HA:};
HA:
HA:if ($@) {
HA: warn error - probably a violation of the unique constraint;

btw, this subject is off-topic for this list. if you are still having
problems, you probably should post your questions to a more appropriate
list. perhaps perusing http://dbi.perl.org/ will yield a better forum for
your questions.

this is an html specification. To affect data or text in the cells each cell
must be formatted with the desired attributes.
Check W3C HTML 4.01 spec.

RE: Escape Characters
I have used the \, and the sendmail then worked. I was looking for something similar to the PHP addslashes(). Or maybe replace, like replace(strAdd, @, \@).

Re: cgi text color in tables

To affect data or text in the cells each cell must be formatted with the desired attributes. Check W3C HTML 4.01 spec. You can mix in standard html pretty much anywhere you need to when writing CGI. Consider: start_Tr, th(font color=redKey/font), th(Value), end_Tr; gives me 'Key' as a table header in red. And if I define: my $bfr = font color=red; my $ef = /font; then start_Tr, th($bfr, Key, $ef), th($bfr, Value, $ef), end_Tr; does the same. (Note if you are not familiar with start_Tr, by specifying use CGI qw ( :standard *table *Tr); the table method can be realized as start_table end_table pairs and table rows can be realized as start_Tr end_Tr pairs) HTH -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
