"If it [Turbo-Ada] is to compete with Turbo-Pascal, it had better be
written in hand coded assembler"

I think that's a wrong conclusion. In fact I think that Turbo-Pascal is
disappointingly slow given the fact that it operates in memory and is
written in assembler. I would think it should be ten times faster than
it is under these conditions. My hand coded scanner and parser for Ada
runs at nearly 3,000,000 lines a minute on a top end PC, so I would
certainly think that a complete compilr (generating pretty straightforward
code, as TP does) should be able to achieve 500,000 - 1,000,000 lines/minute.

Another point of comparison is that Turbo-Pascal is not significantly
faster than Realia COBOL, but the latter compiler is written entirely in
COBOL and is a six pass compiler that definitely does *not* keep everything 
in memory (in fact even the symbol table is on disk, though of course these
disk files are in practice buffered in avaiolable memrory wheere possible).
