Anita, it is possible to set up an object directory, but not that way,
because gnat was designed to be used in conjunction with a library
manager. One of the simplest library managers is to create an object
directory (perhaps using the subst or mkdir commands in DOS). In your
batch file that compiles files, you could copy the file being compiled
into the object directory, chdir to that directory, compile it in that
directory, then chdir back. That way, the entire directory is safe for
deletion at a later time, because the source code files it are merely
copies, just like in a real library management system. An example of
such a batch file is:

 @echo off
rem GNATC1 copies a gnat file to the library (t: or u:) then compiles it

rem     Parameter Usage: GNATC1 (NAME) (EXT) (DIR)
pushdriv
if exist d:onlytest.ing goto t
  copy %3%1%2 u:
                      echo COPIED %3%1%2 u:
  if errorlevel 1     goto notfound
  if not exist u:%1%2 goto notfound
  u:
  echo         GNAT compiling %1%2 in u:
  goto compiling
:t
  copy %3%1%2 t:
                      echo COPIED %3%1%2 t:
  if errorlevel 1     goto notfound
  if not exist t:%1%2 goto notfound
  t:
  echo         GNAT compiling %1%2 in t:
:compiling
  echo on

REM if just syntax checking:

  redir -eo gnatf  %1%2

REM if compiling (add whatever additional parameters are desired):

  redir -eo gcc -c %1%2

  echo off
  if errorlevel 1 goto bad
    popdriv
    goto :end
:notfound
  echo gnatc1.bat could not copy file %3%1%2
:bad
  echo gnatc1 compile failed
  popdriv
  exitcode 2
:end

This batch file assumes that there are  two library directories which
are SUBSTed to drives T: and U:. The T: drive contains the test files,
while the U: drive contains the utility packages used by the test files.
This arrangement is convenient because you seldom wish to delete your
ADTS, I/O drivers, task types, protected types, and distributed
persistent objects. However, you will often want to delete the object
code and executables from test programs, because they are big. During
software upgrades on tiny machines a batch file can be set up to link
and run each test program, deleting the T: directory after each
executable is executed, so the space is continuously recycled, while
keeping the U: directory.
