I have been using Ada quite successfully since about 1991 - non defense/non aerospace companies. The projects are _hard_ real-time, embedded (we design our own embedded hardware) and safety critical. In fact being safety critical, the software _has_ to meet its deadlines otherwise there could be some serious problems :) The compilers (2 different manufacturers) I have used have generated assembly that was very efficient and there was not much code bloat. Admittedly the projects were based on 68332's or 68030 (not exactly 8051's) and we had about 512KB of ROM space with 256KB RAM. 1 project we used Yourdon/Ward-Mellor Real-time extensions as the methodology. The other 2 projects were done using Shlaer-Mellor OOA. -- Rakesh
