Instead of screening out certain numbers, you might also just start at 
32, anything below that is a control character. You might as well stop
at 127 too, since that's where ascii ends, anything above that will
show different characters on different systems (DOS or UNIX).

Here's a program that does exactly the same as the above, but in pascal:

[begin pascal source]

program show_chars(input,output);

var x :  integer;

begin
  for x := 32 to 255 do begin
    writeln(x,' ',chr(x));
  end;
end.

[end pascal source]

On my unix sys I compile this with: pc progname.p -o progname
When running TurboPascal, you might need to include something.
