Sounds pretty good to me - infintely better than my Ukrainian (or whatever
is your native language)!

If you are not already familiar with Oberon-0, it is documented in Wirth's
Compiler Construction book which you can download from:

http://www.oberon.ethz.ch/books.html

You can download the BlackBox version of the compiler from Helmut Zinn's
site:

http://www.zinnamturm.eu/downloadsOS.htm#Oss

My initial target is to implement the minimum required to make it
self-compiling so it can be propagated in the same way as Pascal-P was in
the 1970's. To Oberon-0 I've added pointers, chars, strings, REPEAT loops,
Forward procedures, SIZE, ORD and CHR and enhanced the assembly code
listing.

I've removed nested procedures (not as crucial as they were in Pascal now we
have Modules). Value parameters may also go once I have IN and OUT
parameters working in addition to VAR for all data types. I'm currently
working on EXPORT and IMPORT - there would not be much more required than
that to enable it to compile itself.

Anyway, we should continue this conversation off-line as it is straying away
from BlackBox and probably of little interest to others here. I'll send you
an email with more detail in the next few days.
