have written a perl file and I need to invoke this from my wft file. How can this be achieved?

The depends on what it is supposed to do for you and during which phase of the WFT processing you want to invoke it.

If you want it to be a workflow task, I suggest using an <external task>.
set a variable to contain the the entire command line. I do something like this.

$perlexec = "/path/to/iwperl";
$myperlcmd = "/path/to/my/perlscript.ipl -myswitches myparameters";

$mycmd = "$perlexec $myperlcmd";
$mycmdXML = "<qq(<command v=\'$od_cmd\' />);

Then down in the XML for the external task, between my <successors> and my <files> i have the following:
</successors>
__INSERT__($mycmdXML);
<files>

-----------------------------------
Now if all you want to do is run a script in the middle, perl gives you several ways to do that. Again, having your entire command in a variable is a good idea:

you can say:
system($mycmd);
or
`$mycmd`
or even use exec or open it on a pipe.

There's more than one way to do it.

Hope I've been helpful.
Len.
