Hello all,
I need a short objective compare of the possibilities of M2 and C but I
don't know much about C (when I see a program then I only can say that
it is written in C or not :-) and I currently don't have enough time to
read through a whole C book. So I ask you to help me please. I have
tried to list the features of the two languages, from the view of a M2
programmer. Would you please be so kind and fill in the missing entries
(or correct them) and then send the list to HPA111@DE0HRZ1A.BITNET
