Using bitwise operators to create boolean flags

I recently learned how to use bitwise operators to create 8 boolean flags using a single variable.  The purpose was to create a character map where I could define customized qualities, similar to the built-in lib functions like isalpha, isdigit, etc.

But suppose I want to have 16 flags?  I tried using a short instead of a char so I get 2 bytes to work with, and thus 16 bits to use as boolean flags.

But, I must be doing something wrong because when I change use a short array rather than a char array, I get results which are off sometimes.

Here I have 10 customized flags:

#define ALPHA 0x0001
#define NUMBER 0x0002
#define UPPER 0x0004
#define LOWER 0x0008
#define PUNCT 0x0010
#define DELIM 0x0020
#define STOP 0x0040
#define SPACE 0x0080
#define CURRENCY 0x8000
#define ELEMENT 0x0103

Then, I go through the first 127 characters like:

unsigned short __charmap[] = {
   DELIM | STOP,
   DELIM | ELEMENT,

...etc.

Yet, it doesn't work properly.  Can anyone spot something I'm doing wrong?
