Re: Newbie wanna Ada

Welllllll....... Let's be careful not to overstate the case. In porting
between a Sun Unix platform and a Windows platform, I have experienced some
byte sex problems, so if not designed properly, there *can* be some
difficulty with porting. With different compilers, there might be problems
with sizes for standard data types between platforms, although I don't
recall ever experiencing those directly for workstation ports. Clearly, if
one connects to platform-specific features, there will be problems with
porting. Or if one relies on compiler-specific packages, there will
potentially be porting problems. It isn't purely automatic.

Having said that, I can still testify that for command line oriented
programs, I have accomplished ports between Unix/Windows/VMS using the Gnat
compiler and it pretty much degenerated to a recompile of the sources. But
you *do* have to take some care in the original design to make sure you are
accounting for machine dependencies.
