Any way to dynamically call a subroutine 2

[cdlvj]

Listers,

I have a perl event ftp processor, which is driven by a .ini file.

Is there any way to call a function based on what is defined in the .ini file.

ie.

[txt]
destination=ftp.someserver.com
preprocess=foo
[dat]
destination=ftp.somewhereelse.com



Would like to have a line if preprocess is defined, to call the foo function.

Do not want to have a large if condition test for each possibility.

use a hash that is a reference to subs:

my %coms = {
   foo => \&foo,
   bar => \&bar,
}

You can also store the content of field [tt]preprocess[/tt] into a variable, then:

$preprocess='foo';
$returnvalue=&$preprocess(@args)if defined&$preprocess;

The [tt]if defined[/tt] works for both conditions, when $preprocess is [tt]undef[/tt] or null, and when [tt]sub foo[/tt] is not defined.
