Maxim Senin <maks@tech.swh.lv> points out that
     i : Integer := Integer'Value ("m");
raises Constraint_Error.

Right.  Instead, use

     I : Integer := Character'Pos('m');

Note the single tic marks around the m.  Since 'm' is of type Character,
Character'Pos converts from Character to an integer type.  To go the other way,
Character'Val(109) converts from an integer type to Character.  The attribute
'Value converts from type *String*, and 'Image converts *to* String.  Thus
Integer'Value("123") is 123, and Integer'Image(123) is " 123".  HTH.
