Would somebody like to define the difference between a 'program' and
a 'script'?
A program is something you write to achieve an end, and goes out and
does "the right thing" appropriately invoked. A script is a a program
that is interpreted by an interactive command processor in lieu of
being entered directly. An executable is the form of a program that is
actually used when it's run.
It seems to me that setting the Shell prompt to "Hello World" does
not satisfy the requirement for a 20 byte program to display that
string, neither does 'echo "hello world"' etc.
I half agree. The 20-byte script is a program. A script that sets the
shell prompt to "Hello world" is a program with a different end.
Setting the prompt isn't a program - no executable, and it prints the
string everytime a program is through being invoked, not on demand.

Nahh - all you have to do is say that the request to execute "hello world" is to press the return button... Personally, I veiw the thread that lead up to this as a proof that echo "hello world" is *not* a program - by the technique of reduction to absurdity.
