Thanks for the reply.
Its not indenting it. when I do M-x cperl-mode, there is no effect.

Thanks

Start Emacs without any init files:

emacs -q test.pl

Then do

M-x cperl-mode

Type in a short program, e.g.

#!/usr/bin/perl

if (scalar @ARGV)
{
print "indentation test here\n";
}

Does line 5 not indent when you hit TAB? It does for me.

It's not designed to automatically re-indent the current file.
Any new code you enter will be indented according to style,
as well any line you press 'TAB' on. To set the particular
style, use cperl-set-style - my personal favourite is 'C++',
even though it has problems with multi-line lists.

There's also 'perl-mode', which again will not automatically
re-intent any of your buffer. It's a bit less colourful, but
just as functional as 'cperl-mode'.

amazed, it was awesome, recognised every word I said. Then I said the
wrong word ... and it typed the right one. It was actually just
detecting a sound and printing the expected word! -- pbhj on /.

Yes. TAB Does the magic. But when you are writing tons of line, you
can not press tons of TABs.
So is there any block indentation technique? VIM has this feature.

For any region you can use C-M-\ (indent-region) or you can also use C-j
(newline-and-indent) instead of Enter (newline) when writing the code.

You may use perltidy.

I have inserted the following code in my .emacs, then C-c t will do the job on any marked region.
If you use activeperl, perltidy will be located in "Perl_Directory"/site/bin/perltidy
