[Squeak-ev] Frage zu "block valueWithArguments:" in Etoys 4 und Squeak 4.2

[Francisco Garau]

Hi - in the first case, x, y and z are variables and you are passing their
values to the block.

In the second case, the values inside the array #(x y z) are the symbols #x,
#y and #z. Try the following:

block valueWithArguments: (Array with: x with: y with: z)

or

block valueWithArguments: {x. y. z.}

The last case is not standard Smalltalk - it's a very convenient syntax
sugar on top of Squeak.

Entschuldigung, aber ich habe fast alles mein Deutsch vergessen.

- Francisco
