  I think you mean it compiles fine, but it doesn't execute fine.

>raised ADA.IO_EXCEPTION.NAME_ERROR : s-fileio.adb:869
  You might look at file s-fileio.adb, line 869, and see what it's
trying to do.  Better yet, use the Gnat facilities for printing a
walkback so it will show what line of your program caused the problem.
I used a compiler that prints walkbacks of user, not library, code
and got:

** Unhandled ADA.IO_EXCEPTIONS.NAME_ERROR
   File not found on open - Map
On Line Number 159 In MAZECREATE

You probably want a Create, not an Open.

  Your prof or TA should be helping you out.
