Adv Perl Programming book - Typo ? 1

[latch]

Hello All ,

Ive been going thru typeglobs again and I ran into this code from Sriram Srinivasan's Advanced Perl programming book


================================================
sub generate_greeting {
my ($greeting) = @_;
sub { print "$greeting world\n";}
}
$rs = generate_greeting("hello"
# Instead of invoking it as $&rs(), give it your own name.
*greet = $rs;
greet();
# Equivalent to calling $&rs(). Prints "hello world\n"
=================================================


I think the "Instead of invoking it as $&rs(), give it your own name." has a typo.

Ive read this many times over before I ran the code.
You really cant invoke the anonymous subroutine by

$&rs();
right?

&$rs();
worked for me


Pardon me ...this might appear trivial ....but after a long gap everything looks new to me.


regards

Yep, quite right.

$&rs() doesn't work

&$rs() works Mike

Actually, that author had many errors. I think it's him. Bcause I checked one of his script from the book and it says 'hour', instead of '$hour'. There is no Knowledge that is not power.

I guess he didn't take the time to create a few perl scripts to check his writing =)
