[Newbies] String construction and replacement

[Sebastian Nozzi]

To all whom I wrote that I found it strange that there was no class
method to construct a String from an array... I was wrong!

I debugged Randal's suggestion of using "as: String" and the result
that "newFrom: aCollection" is called. So, the solution could also be:

string := String newFrom: {$H.$I.Character cr. $T.$H.$E.$R.$E}.

Of course, to make it completely portable you could also use two ways
that have been suggested: add every character into an
OrderedCollection and use that, or use a standard array-literal and
manually #put: the carriage-return afterwards.

Thank you again for your answers,

Sebastian
