Variable call subroutine?

Posted by TedH (TedH), 5 January 2007
Hi Graham, can a variable call a subroutine in Perl?

For example:
Code:
$myvariable = "&subRoutine;":
(I know this doesn't work)

Code:
$myvariable = "\&subRoutine\;";
(Neither does this)

The object is create a file from a template which itself will have variables that are already used in a script. I can create the file from an HTML template, but it's a "set" thing. I'm looking for more flexibilty.

Any ideas?

cheers - Ted

1. This works:

Code:
sub hello {
       print "hello world\n";
       }

$subname = "hello";
&{$subname}();


2. Be careful

3. Consider AUTOLOAD

4. Happy New Year

Thanks, and Happy New year to you too  

Looks simpler than I thought it would be if it could be done.

I'll give that a go and check out AUTOLOAD too.

cheers - Ted
