Excuse me, but you omitted my final line
       In short:  I would like to have it back ;-).

I am aware of the fact that the entry keyword was never specified and
implemented.  My preceding sentence was thought as joke with a serious
core (to spell it out: if there had been an implementation of multiple
entry points into C functions, I could think of reasonable uses for it).
The joke was marked as such.

I have no access to an implementation of C++ (it is difficult enough to
get a working version of C on MVS here), so your suggestion is welcome,
but hard to follow. Moreover, whe have a quite good SIMULA compiler
here, so for object oriented programming a tool is at hand.

SIMULA is a general purpose, object oriented language (the first one, I
think) based on Algol, which I can recommend to everyone :-).
