For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
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
