Cedric,
Thanks very much. That works for the hello() function, but not exactly
for the five() function. For instance, if I have
function five()
return 5
end
five()
Then I get no output when calling from the Command Line, while I do in the
REPL. In fact, in the REPL I get the output after include("five.jl") and
then again when I call five(). That make sense to me. To get output at the
Command Line I need to replace "five()" with "println(five())" or change
the "return 5" statement to "return println(5)". Why is there the
difference in behaviors? It's not a big deal, but it does seem like an
inconsistency in how functions behave in the REPL and at the command line.
I seem to remember encountering a difference in behavior between the REPL
and IJulia. Is there a document the lists the differences in Command Line,
REPL, and IJulia environments.
Thanks,
Rich
