[comp.lang.ada] A transportability data point

contr47@nosc-tecr.UUCP ("CONTR47") (12/19/86)

The GKS/Ada device independent code is about 130,000 lines of code.
It was developed on a Data General Ada system and ported to Dec
VAX Ada system. About 100 lines of code had to be modified,
maily for 2 reasons; 1. Bad code accepted by DG and 2. Good code
rejected by DEC. The code was designed for portability so it is no
surprise that porting problems were compiler problems. I believe that
within 5 years ywe will see these sort of problems go to near zero
and then portability will be mostly a design problem.
