Unfortunately, the program you supplied would not compile.
There is no Text_IO.Put_Line procedure with a parameter
with the formal name "Last."

I slightly reworked your program as follows:


procedure Show_Debugger_Problem is
    Line : String (1 .. 100);
    Length : Natural;
begin
    Ada.Text_Io.Put ("Enter Line : ");
    Ada.Text_Io.Get_Line (Item => Line, Last => Length);
    Ada.Text_Io.Put_Line ("You Entered """ & Line (1 .. Length) & """");
end Show_Debugger_Problem;

And, to answer the previous post....

As with almost all GNU programs, typing the command name with the
single argument --help yields information about command line switches.

For gdb:

[d:/gnat_examples]$ gdb --help
GDB 4.16.gnat.3.11b-1 (i686-pc-mingw32),
Copyright 1996 Free Software Foundation, Inc.
This is the GNU debugger.  Usage:
    gdb [options] [executable-file [core-file or process-id]]
Options:
  --help             Print this message.
  --quiet            Do not print version number on startup.
  --fullname         Output information used by emacs-GDB interface.
  --emacs-gdbtk      Enable emacs-GDBTK interface.
  --epoch            Output information used by epoch emacs-GDB interface.
  --batch            Exit after processing options.
  --nx               Do not read .gdbinit file.
  --tty=TTY          Use TTY for input/output by the program being debugged.
  --cd=DIR           Change current directory to DIR.
  --directory=DIR    Search for source files in DIR.
  --command=FILE     Execute GDB commands from FILE.
  --symbols=SYMFILE  Read symbols from SYMFILE.
  --exec=EXECFILE    Use EXECFILE as the executable.
  --se=FILE          Use FILE as symbol file and executable file.
  --core=COREFILE    Analyze the core dump COREFILE.
  -b BAUDRATE        Set serial port baud rate used for remote debugging.
  --mapped           Use mapped symbol files if supported on this system.
  --readnow          Fully read symbol files on first access.
  --nw               Do not use a window interface.

For more information, type "help" from within GDB, or consult the
GDB manual (available as on-line info or a printed manual).
[d:/gnat_examples]$

The other method which answers a significant portion of the questions
posed about GNAT on this newsgroup is to read the wealth of documentation
provided with GNAT.

This method would have also told you about the -nw switch (which is quite
common for GNU programs, by the way).
