Talk:Jensen's Device

From Rosetta Code

It is amazing how wrong some ideas of early computing were. Fortunately none of modern languages really supports this mess. --Dmitry-kazakov 11:53, 22 November 2008 (UTC)

I don't think the guys in the 1960's had a monopoly on bad ideas... take the new "\" (back slash) operator in PHP[1] as an example. Fortunately, every now and then, a good idea floats to the top, the trick is being able to spot the good idea early and rewind all the bad ideas even earlier.

Seeing an entry on Jensen's Device just floats my boat.

Not knowing much about ALGOL60, I'm curious about its semantics -- why is i declared twice? When iterating over i, is that value being assigned local to sum, or is it being assigned in sum's caller? --Saccade 21:50, 5 May 2011 (UTC)

i is passed by reference to sum, the "first declaration" represents the declaration of the storage and the "second declaration" is the declaration of the type of the argument (much like a K&R C parameter list) in the parameters for sum. --Rdm 21:57, 5 May 2011 (UTC)
