Calling Methods - (Dan Ragle)

When calling a method of an object, you typically use this syntax:

$myObject->method_name($param1, $param2);

So your example was almost right, except that you do not need a '$' in front of the method name itself. And remember that when that syntax is used, Perl automatically sends the object itself as the first parameter to the method; thus the first line of methods is often something like this:

sub myMethod {
   my $self = shift;

Good luck!

calling method using variables - (Brad)

I have an object, function name, and
parameters and I want to call it. What's the right syntax?

my $result = $myObject->$func($parms);

That doesn't work....

Well written! - (Sham)

Well written topic minus all the clutter. The focus was clear, with emphasis on the concepts. Now I am able to understand/write subroutines better. Thanks for sharing this with us. I am sure it's going to help many.
