   ALERT ALERT! don't fall into the remarkably common trap of calling your
   main program test and then trying to execute it with the command

      test

   which in Unix will typically do nothing.

   We get this bug report all the time, once complete with a long diatribe 
   about how GNAT was completely useless.

   (test is an internal shell command in Unix, either use some other name, or
    execute the program using ./test)

   :-)


Yes, good suggestions. Also one can add "." to the $path (edit
the .cshrc or .profile etc..) , make "." be the first in the path, 
and when one invokes test, the shell will first look in . which is 
the default current directory and use your "test" program , not the
one in /usr/bin .

I think it is not very smart of unix to call one of its images such
a generic name as "test" . But again, this is unix, if they did not
do such weired things, they will no longer be unix, but on the other
hand this is why we love unix, it is just different, and can surprise
one at any time, so it makes it interesting and more fun to work with 
it.

thanks,
Nasser
