$@, $< and $**

[areza123]

What is the significance of each of these in Perl

$@ - i think this indicates a parameter but to what and where ?
$<
$**

I have found these in my make file which I use with nmake utility.

From 'The Camel'...

$@ is the error message from the last eval command.

$< is the real user id of the process that is the perl script that contains it.

$* is an old (deprecated) switch that tells perl whether or not to assume a string is a single line.

I'm not what $** could possibly mean though.

Hope this helps
