** charmap.h : P0 specific, also included by charmap.c
|
|
** it defines the mapping used to go from simple chars to these predefined
|
|
** values. this enables the compiler to use a compact switch stmt.
|
|
** they have been grouped in what is believed to be the most beneficial
|
|
** way, in that most switches will be checking those values which have
|
|
** been grouped together.
