 Which manual is this?

 SIMULA was the first object-oriented programming language and all
 object-oriented products (C++, Eiffel, Smalltalk, .....) are derived
 from SIMULA and its concepts in some manner. SIMULA started out in the
 early 60s as an extension of ALGOL 60 for the purpose of doing
 discrete event simulation. Later, still in the 60s, the concepts were
 broadened to address the problems of constructing complex software
 generally and this new version, which exists to this day, was a truly
 general-purpose programming language. It retained particular support
 this was provided as a specific application of the features of the
 basic language.

 For a variety of reasons, SIMULA never attained massive popularity but
 it had enormous influence on the design of many of the prominent
 modern languages. Despite its age, it is still ahead of some of them
 in concept.

 When you ask for code examples, are you interested in simulation or
 general-purpose programming? I can probably dig up some examples.
 There may also be some examples archived in the SIMULA LISTSERV list
 through which your enquiry reached me. If you only want a rough idea
 of what SIMULA is like, there are a couple of papers in our FTP
 archive which I have written. One is about SIMULA generally. The other
 is about object-orientation in simulation and page 10 onwards should
 give you an idea about how to do simulation in SIMULA. Pages 1 to 9 of
 that paper talk about how to provide simulation support in
 object-oriented languages which do not cater specifically for
 simulation. These papers are, respectively

        sam.ps.Z and oosim.ps.Z

 in ftp.newcastle.ac.uk: /pub/local/nrk/doc

 Hope you find this helpful.

 Cheers....Ron
