Can I combine this thread with "Source code layout question" and ask "why the prefixed colons?" n: :n + 1 Unless I'm missing a subtle syntax issue or speed optimization, that's the same as n: n + 1 although I can see that it does lead to a slight bit of additional orthogonality in something like: mySeries: [1 2 3 4 5 5 6] n: :n + 1 print :myseries/:n where the 2nd colon is needed in the print statement. Pity we can't write: mySeries: :[1 2 3 4 5 5 6] for complete consistency <g> Sunanda. -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
