Re: DEC Ada and packages

Just be sure to try to get a grasp on the fact that file naming and
compilation unit organization is something that can vary some from one
compiler to another. The DEC Ada compiler will let you pile multiple
compilation units into the same file because its first step is to enter them
into the "Library" so it can sort out compilation units, dependencies and
what is out of date. Whereas the GNAT Ada compiler uses a native file system
directory to be its "Library" and utilizes the file names and timestamps to
locate compilation units, resolve recompilation issues, etc. (Maybe not 100%
accurate as I'll probably hear about later, but close enough for now.) Hence
GNAT tends to care about the names of files and requires 1 compilation unit
per file. Its not hard to live with once you get used to the tools, but its
a factor you want to understand as you build Ada software.

For more tools, books, tutorials, etc., be sure to look at:
