Try

[seti somevar]Hello World! This is a very long description bla bla bla bla
bal bal bla
[/seti]

[perl arg=scratch]
        $a = $Safe{'scratch'}->{'somevar'};
        $Safe{'scratch'}->{'somevar'} = substr($a, 0, 12);
        return '';
[/perl]

<BR>

TEST: ****[scratch somevar]*****<BR>

and you will get

TEST: ****Hello World!*****

You can use

[seti somevar][item-field varname][/seti]


Regards,

	Joachim
