in thread Using perl to teach programming

You could store the script lines in a list instead of a single scalar, then using (ack!) line numbers, provide a way to list, modify, add (remember BASIC?), or delete lines. This way a tutorial can build up a routine. Then at the end, you can save the whole thing as a real Perl ".pl" script in an external file.

Does this remind you of BASIC or what?

    Yeah, add a LIST command, which will show all those lines, possibly preceded by line number (and automatic renumbering), so you'll be able to fit lines in between them:

    >LIST
10 while($home) {
20 sweet }

>15 # Okay, a ++ vote for the first monk to recognise which tv series 
+I'm referring to :-)

>LIST
10 while($home) {
20 # Okay, a ++ vote for the first monk to recognise which tv series I
+'m referring to :-)
30 sweet }

    Problem is, BASIC has a bad reputation, but this 'instant gratification' 'mod for Perl' might be very promising. I'll try to test it on my brother tomorrow :-)

    This sounds reasonable. The abiliry to create 'real' working little scripts is simply a good way of 'getting a feeling' for things. If the beginner would see some nicely formatted and correctly indented code, it would it could well improve his or her understanding. You could even go one step further and use the line numbers to output listings like we find in magazines. Maybe even HTML(orwhatever)-style. OK, you're probably right that this would mean a lot of effort ;-)

    The list-storing-method would mean command-history, too (or did you think of theat already ichimunki?)
