Hi Wisecracker,

I am not assigning as such.
AMIGA:barrywalker~> VAR_VAL=$VAR1

I am assigning like VAR_key=$1 ($1 is the input to the script)
$1 will be VAR1

I want to retrieve the string that is present in VAR_key. That is what I am trying to do here,
extracted_variable=`echo "$[$Var_key]"`

<B>@RudiC </B> : Variable will not have a text with spaces. It will be a string like this.
"THIS_IS_A_TEXT".

Thanks.

Pod::Simple::LinkSection(3)				User Contributed Perl Documentation			       Pod::Simple::LinkSection(3)

NAME
Pod::Simple::LinkSection -- represent "section" attributes of L codes SYNOPSIS
# a long story DESCRIPTION
This class is not of interest to general users. Pod::Simple uses this class for representing the value of the "section" attribute of "L" start-element events. Most applications can just use the normal stringification of objects of this class; they stringify to just the text content of the section, such as "foo" for "L<Stuff/foo>", and "bar" for "L<Stuff/bI<ar>>". However, anyone particularly interested in getting the full value of the treelet, can just traverse the content of the treeleet @$treelet_object. To wit: % perl -MData::Dumper -e "use base qw(Pod::Simple::Methody); sub start_L { print Dumper($_[1]{'section'} ) } __PACKAGE__->new->parse_string_document('=head1 L<Foo/bI<ar>baz>>') " Output: $VAR1 = bless( [ '', {}, 'b', bless( [ 'I', {}, 'ar' ], 'Pod::Simple::LinkSection' ), 'baz' ], 'Pod::Simple::LinkSection' ); But stringify it and you get just the text content: % perl -MData::Dumper -e "use base qw(Pod::Simple::Methody); sub start_L { print Dumper( '' . $_[1]{'section'} ) } __PACKAGE__->new->parse_string_document('=head1 L<Foo/bI<ar>baz>>') " Output: $VAR1 = 'barbaz'; SEE ALSO
