I used the code above when I was first learning Perl to test
snippets of Perl code interactively. G'head ... try it. From
a command prompt ( or shell prompt ) type:
perl terp.pl
You should then see a weird little prompt:
->
At the prompt type the following:
$x=4*7;
print $x;
You should see instant results.
This can be very handy for tinkering with regex's and such. I had meant to build in a command-history, but never got around to it.
