I have the following code

self workSession attendees do: [:each | html text: each person

separatedBy: [html text:'; '.]
if there is no attendees for my worksession, it needs to display : NO
ABSENTEES.
You can assign subexpression (self workSession attendees) to a temporary
variable wsa and after the statement (wsa #do: ...) have another statement
like this
wsa ifEmpty ifTrue: [what you would like to do if there is no
attendees].
HTH.

They have been around longer than some people on this mailing list ;-)
i've been poking around and cant figure it out.
true and false and some of the very few objects known to the VM and they
where instantiated when the parent of all current images was created.
All images are basically cloned and not re-created from source, and
that's why you don't see any initialization code for them, they just
are.
Hope this doesn't add to any confusion...
