For background only (I think my question is simple): I'm new to ruby,
read the book etc and now trying my first conversion. I'm doing this in
two stages since I'm still getting familiar with Ruby syntax. First stage
is to take my existing PureBasic code (think C without any of the junk)
and try to implement the Ruby equivalent line-for-line. Second stage I'll
completely redesign it in true Ruby fashion. My PB program is an
automated downloader where I supply a list of URL's and the "Download
Manager" (DLM) part handles "Requests" by creating a thread for each one.
The DLM itself is a thread so I can schedule the downloads say every 10
mins. Now my question...
So far I have created classes for the DLM and Requests. To track the
states of both I use constants declared (in PB), for example as...
....which does the same thing (in this case I don't care about the actual
values).
So what is the nearest Ruby equivalent? I'd want it class-specific so I
don't need the DLM_MS_ part and where I don't care about the actual value
I guess I'd use symbols? Any/all tips appreciated!
PS: I already know that when I do a proper redesign I'll probably use
queues to represent the states of individual requests. My problem of how
best to represent/implement constants/enums extends to other code I want
to convert.

You can define constants per class, you can use an existing enum
implementation (to be found in the RAA) or you can directly use symbols.
Disadvantage of the latter approach is documentation: you don't have a
single place where all are defined.

I love :symblos
However, the above is another disadvantage.
If you misspell one, noone :screams about it, and they have such tiny :colons they are hard to :spot.
