Why do you want to do this?  In C and C++, a char can be automatically
converted into an int.  The resulting integer contains the ASCII code of
the character.  For instance,

int	sample = 'X'; /* sample == 88 on most systems */

Is this _really_ what you want to do?  It's perfectly legal, and will work
as advertised as long as you know what you're doing.
