   I agree with Randy with one caveat: 
   The front-end of the compiler should be the same as the one used for
normal compilation; however, the environment should include a group of
precompiled packages (such as in .Net or the Java environment) together with
a very fast link and bind.  This would help for common actions like the
management of directories or code development.  Presently GNAT employs a
specialized Ada like language for their development environment; Alsys had
Ada World. Given the speed of the front ends of present Ada compilers, I
believe that this part of Ada compiler is suitable for creating batch files.
The error messages would be a significant benefit.

      That's funny, because if it's complicated enough that I can't write a
batch
      file to do it, I'll generally write it in Ada. Bat has If and Goto,
and that
      is enough for simple tasks. Beyond that, I want to be able to fix it
and be
      able to insure that it works...

Doesn't BUSH's AdaScript begin to fit this niche?

BUSH looks very good, but it does not run on Windows. It is rare to have
scripts only on GNU/Linux... If ported to Windows it would be a very nice
cross-platform scripting environment.

This is one of the reasons I started the AdaCL projects. Main goal here was
to provide a framework to write scripts directly in Ada.

Was it a success? I still don't know. The Scripts work fine with Windows,
OS/2 and Linux. But it does take a little more time to write them. But then
they are more robust then for example Bash.

The other thing that spoke against Bush: It is not feature rich enough -
yet. I did some Bush scripts and then hit the limit of Bush. The most
problematic part was the the handling of the current working directory.
