When you have to maintain a large commercial program that must run on NT for some customers, on Linux for others it's perfectly feasible in Ada (real case). Try just to manage accurately file I/O in a portable way in Pascal, even details like 'what happens when such file is not there ?'. Not to make the hot-line explode... Another important thing: you should have the choice between compilers, even when your program already has more than 100'000 lines. E.g. switch from a compiler firm A (which suddenly closed down, stopped development, begins to procude a unusable bloatware, has too expensive support or doesn't provide optimization or a Linux version) to firm B or C. > >Ada is kind of like > >"Pascal++" in that the syntax is very much like Pascal's, but it cures > >certain ills that existed there and then added a *lot* more stuff to > >make the language much more powerful. > Over standard pascal, or over Delphi? Anyway, a lot over BP7. I find even Ada 83 (current is 95) with its generics (templates), polymorphism, overloadable operators, subtypes a quantum leap for programming numerics (here on an Alpha server) compared to BP7... I would be glad to incorporate some details about Delphi in my comparison... ______________________________________________________ Gautier -- http://members.xoom.com/gdemont/gsoft.htm
