Stings - textareas in Perl...

[joesplink]

This seems odd.

Indeed. The second example is clearly bugged.... and why my strings
were growing. However, the first example, which seems kosher to me,
causes me to lose trailing cr-lf's. But, wait a minute..... I actually
prefer to get rid of those trailing cr-lf's anyhow....and have added a
little code to do it explicitly (courtesy of my Perl book)....so, I can
live with the first version....especially since I won't have to .....

Thanks for your help.

The reason I convert the lf's before writing to disc is because I want
to read the disk file with

my @array = <DATAFILE>;

and if I write the string with embedded lf's it will come back as
multiple array elements.

Not if you do it right. Look at the perlop page under $/.

Check... see that I must insert <br>s in the HTML.

If you want to preserve newlines and multiple spaces, use <pre>.

Even if I set my $Field="A\r\l\r\l" I still get back only "A"......

Don't blame perl for that: the behavior is browser specific.
And it's "\r\n" not "\r\l".

So, (at least part of) the problem is I don't know exactly what string
Perl is sending to the browser in the above instances.

You mean you've never used the brower's View Source feature?

"Why don't these 2 snippets send the same output to the server?"

Don't you mean "from the server"?

"exactly what do these scripts send to the server?"

Send to the _browser_.

The perl answer to that is 'use LWP::Simple;'.
