[Newbies] appending Strings

[Mariano Abel Coca]

I think you must be thinking in #timeToRun.

About that... In VisualAge there are the EsbTracer and EsbSampler, which
allows you to meassure the time that involves every message sent. It's
useful to tune some code... But don't know in Squeak. Any ideas?

Cheers,
