Another book worht picking up is Burns' and Davies' "Concurrent
Programming"(Addison-Wesley, ISBN: 0-201-54417-2).  It uses Pascal-FC
as the promary language, but it also discusses Ada95 in there.  The
Pascal-FC language actually adopts the "protected type" syntax of
Ada95, so the mapping is relatively isomorphic.

      Frustrated with C, C++, Pascal, Fortran?  Ada95 _might_ be for you!
	  For all sorts of interesting Ada95 tidbits, run the command:
"finger dweller@starbase.neosoft.com | more" (or e-mail with "finger" as subj.)
		if u cn rd ths, u r gd enuf to chg to Ada   :-)
