program ASCIITABLE(output);

uses    crt;

const   columncount = 8; {8 columns as 128 is div perfectly by 8}
        columnwidth = 3; {unprintables need 3 spaces, neater output}
        Title:string = ('                              ASCII TABLE          ');

        unprint: array [0..32] of string =(
        {string as below are 'string' variable}

           for i:= 33 to 127 do
            begin

              write ('  ',i:3);

      {  writeln ('             ');     }
        writeln;
        writeln;
        writeln ('Press Return to continue' ,ch);

        read (ch);
              end.

So after playing around a bit, this is what I've got.
It displays Ok, Not as perfect as I'd like it but this is within my scope.

I'd like to be able to use the characters instead...
I can do chr 1 to 7 (these display ok) and 16 - to 127 but it's 8 that causes the problem throws the whole table out.

I like // comments for single line as they work in most programming languages, for ex:

DoSomething;  // comment...
