Hi Danie,

The #( ... ) element is used for constructing an array of literals or
reserved identifiers, compiles the elements statically. See
http://minnow.cc.gatech.edu/squeak/3435.

Short English translation, you can put things like strings, numbers, symbols
and stuff like that into an array using the #( ... ) construct. This does
*not* include variables. In your example, you can't put the lf into this
array constructor because it's a variable.

You are trying to build an array with a variable included. There are a
couple of ways to build your array:

lf := Character lf.
newArray := Array with: $a with: $b with: lf.

will give you an array  with a lf character on the end. Another 'special'
way to build arrays is to use the { ... } construct. In your example:

lf := Character lf.
newArray := { $a. $b. lf }

or

newArray := { $a. $b. Character lf }

(Notice the period after each entry). Conceptually, this evaluates each of
the array entries before actually shoving them into the array.

Hope this helps,

Jim
