The issue is not whether subsets are allowed or not, but rather
whether a compiler for the Pascal subset (whatever that is) could be
used productively for a first course in Ada. Having taught Ada as a
first language for 2 years now, to a diverse group of students of
variable ability, I am convinced that a VERY CHEAP (or FREE) compiller
for the Pascal subset that will run on the old 8088 machines that some
of my students have (yes, without hard disks), would be worthwhile.

I ussed to be, but now am not, sure that we need to cover (Ada \
Pascal) in the first course.
