[Omaha.pm] Perl question

[Sterling Hanenkamp]

Just to muddy the waters, you could run hello world from vim, if you wanted.
Like this:

<esc>:!perl assignment_6

It will show the output and ask you to press enter to get back to editing.
You can also run the current file by using "%" as your file name.

<esc>:!perl %

I find this especially useful with the "-c" option which checks to see if
the perl file can run (though, not whether it will run correctly):

<esc>:!perl -c %

That's a nice quick check for typos.

Cheers.
