Hi Dave!

I was thinking of interactive debug commands.

I believe that you will find in Perl, that the debugger is seldom used because its not required. I have to use a debugger (mandatory) when I write assembly code, I very seldom use a debugger for C code and almost never use a debugger for Perl code - for me, the Perl debugger is a once in a decade event. I have never required the Perl debugger to solve a code problem.

I congratulate you on your curiosity and motivation to learn more about Perl!

Perl is an amazingly introspective language. A Perl user function can find out things that are just not possible for a C program.

Some useful stuff for debugging the caller stack is the Perl Caller() function.

Some "standard" functions:

$me  = whoami();
$him = whowasi();

sub whoami  { (caller(1))[3] }
sub whowasi { (caller(2))[3] }

I recommend study of the caller() function for your "debug repertoire".
