A quickie problem with an array and a right hand bracket

["chris.danx" <chris.danx@ntlworld.com>]

Hello everyone,

I'm trying to provide an array for quickie conversion between numbers and
character equivalents like this

    type array_16 is array (natural range 0..15) of character;

    basic_16 : constant array_16 := ('0'..'9'|'a'..'f');

The compiler corrected me on the use of a comma where the dda ("d divides a",
from math sorry, it's a bar or more symbol) but this doesn't help with
"unexpected parenthesis error" when it's compiled.  What's the problem?  It
looks correct to me but clearly i am missing something (very subtle) point.

In case i get the use text_io and tear off the start and end parts for
displaying in other bases argument.  I do not want to use text_io in this manner
since i want to remove (as much as possible) dependance on the standard packages
(for now).


Thanks,
Chris Campbell
