It's pretty simple. There are things in Ada called "Attributes" which can be
extremely handy for a wide variety of things. In this case, there are two
attributes which are defined for all discrete types (characters being a
discrete type). They are 'Pos and 'Val and they work like function calls.
Here's basically how you would use them.

My_Int : Integer := 0 ;
My_Char : Character := ' ' ;

...

My_Char := Character'Val (33) ; -- Gives My_Char the ascii character '!'
My_Int := Character'Pos ('&') ; --  Gives My_Int the value 38.

A good example of this is in the appendix A.3.3 of the ARM. (This is where
the Latin_1 character set is defined.) If you don't have an ARM handy, look
at: http://www.adapower.org/ under "Reference" for the on-line HTML version
of the ARM. While the ARM is not the best source for teaching yourself Ada,
it is a valuable resource for looking up particulars that you may come
across in reading other texts.

Good luck with Ada!
