Distribution of subrange bounds

Distribution of subrange bounds

[dmjones]

All,

I am trying to find papers on the integer subranges
used in programs.  What are the distributions
of the lower and upper bounds?  What is the
distribution of representable values, i.e.,
the difference between the upper and lower bounds.
To what extent do developers use subranges, instead
of the basic integer type?

Can anybody point me at any empirical analysis
of Ada or Pascal source code?

Thanks.

I've never head of any such study. However, you can certianly go to
http://www.adapower.com and analize a whole bunch of Ada sources
yourself. Free Software projects may not be representative, but it
should give you some idea.
