Quite often when someone wants to do something like that, they had
formerly programmed in some other language whose ability to define
data types is not so robust as Ada.
Except for the particular situation of changing case of an ASCII
Roman letter (for which Ada95 has built-in capabilities), flipping
a bit in a character is totally meaningless.
If you really meant to blip a bit in a data cell that happens to
be 8 bits wide, then please study record and array declarations
in an introductory Ada text. If you have to match some external
standard, such as hardware or a program written in another language,
look at the part about representation clauses.
