In Chapter 2, Figure 2.1 are a little misleading. They give
the impression that C++ was finished in the 1980's and ANSI C was derived
from C++. In fact, C++ was developed from C in parallel with ANSI C and collected
several ideas from ANSI C. The early C++ did not have much effect on ANSI
C. ANSI C was completed in 1989. C++ continued to develop until 1998. ANSI
C++ was drafted in 1997. ANSI/ISO C++ was finished in 1998. See the diagram
I've never known a real COBOL programmer who wrote "PICTURE IS". We all
wrote the shorter "PIC". We always omitted stuff like "IS".
Nobody wrote "LABEL RECORDS
ARE STANDARD" and "RECORD SIZE IS <blah>". The compiler worked these out
My memory of the Ada design process was that both PL/1 and Pascal where

of the 17 early designs even if it didn't make it into the final four.
The book omits a later development! APL finally escaped the "IBM Golf
Ball with Greek letters" environment. There is language called J

the direct descendent of APL that works on ASCII/DOS systems.
