All,

I have been following up on the references posted here (thanks all).

Figure 4 of "Impact of Ada and object-oriented design in the
flight dynamics division of Goddard Space Flight Center",
SEL-95-001 shows a graph of "total types per statement" vs
time (a five year period).  The increase is claimed to be
due to an increase in use of strong typing.

The cited reference is:
"Experiments in software engineering technology" by
McGarry & Waligora.  From SEL-91-006.

This paper does not appear to be available online.
Does anybody have a copy?

How is "total types per statement" measured?
Is it an average of the number of types appearing in the
same statement?
