G'day Steve,

Welcome to the Monastery.

Without any code, it's not possible to advise how to modify it such that you get the results you want.

In brief, you can access arrays using the original name (@array_original_name):

$ perl -E 'my @name = qw{a b c}; say for @name'
a
b
c

You can create an arrayref and access that with the @$arrayref notation:

$ perl -E 'my $name_ref = [qw{a b c}]; say for @$name_ref'
a
b
c
[download]

You can take a reference to an existing array and access that as in my last example:

$ perl -E 'my @name = qw{a b c}; my $name_ref = \@name; say for @$name
+_ref'
a
b
c

I suspect you're doing something wrong, given the "$var='name'" you mention; however, as already stated, without seeing your code, I can't help you with that.

Take a look at "perlreftut - Perl references short introduction". At the end of that document, you'll find links to more in-depth information.

Before posting again, plesae see the guidelines in "How do I post a question effectively?"; also consider using an "SSCCE". You'll get much better answers if you provide all the relevant details.

I try to access the array named @name, by @{'name'} or by using variable @$var where $var='name'.

This is almost always not a good idea, as is explained in this article (Update: Oh, I just saw holli already linked to it). These kinds of questions are usually most easily solved by storing the data in a hash, in this case the structure would be a hash of arrays (link includes sample code, and as the AM showed). At the very least you probably want to use hard references (my $arrayref = \@name;) instead of symbolic ones - see perlreftut and perlref, as kcott said.

so far I have no other choice to use @{'name'} from beginning of my program

Could you show a Short, Self-Contained, Correct Example of this?

I have posted this numerous times across the Internet over the years, and each time I come across it, I read the whole thing again. I find it quite humorous, and at the same time informative.

Why do you want to actually use symbolic reference to use/access a variable?

You could use a hash ....

my %var_map = ( 'one' => [ 1 .. 2 ] , 'three' => [ 33, 43 ] );

my $name = 'one';
print @{ $var_map{ $name } };

If you still have pressing need, justifiable or otherwise, to implement the original intent, look up "symbolic reference".
