+; 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
