[Newbies] [Q] How should one concatenate Strings?

[David T. Lewis]

Hi Charles,

Try something like this:

   '<!', self class name, ';', name, '!>'

The comma character is actually is actually a message that is understood
by strings. The message is implemented in class Collection (in the
"copying" method category), and since strings are types of collections,
it works for strings also.
