; Character specification table.
;
; The tables are readonly, put them into the rodata segment
.rodata
; The following 256 byte wide table specifies attributes for the isxxx type
; of functions. Doing it by a table means some overhead in space, but it
; has major advantages:
;
; * It is fast. If it were'nt for the slow parameter passing of cc65, one
; could even define macros for the isxxx functions (this is usually
; done on other platforms).
;
; * It is highly portable. The only unportable part is the table itself,
; all real code goes into the common library.
;
; * We save some code in the isxxx functions.
;
;
; Bit assignments:
;
; 0 - Lower case char
; 1 - Upper case char
; 2 - Numeric digit
; 3 - Hex digit (both, lower and upper)
; 4 - Control character
; 5 - The space character itself
; 6 - Other whitespace (that is: '\f', '\n', '\r', '\t' and '\v')
; 7 - Space or tab character
