-; 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 weren't for the slow parameter-passing of cc65,
-;     one even could define C-language macroes for the isxxx functions
-;     (as it usually is done, on other platforms).
+; See "LICENSE" file for legal information.
 ;
-;   * It is highly portable.  The only unportable part is the table itself;
-;     all real code goes into the common library.
+; CBM character specification table.

-;   * We save some code in the isxxx functions.

-; 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.

-; 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.

-; The following 256-byte-wide table specifies attributes for the isxxx type

-; has major advantages:
-;
-;   * It is fast. If it weren't 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.

-; 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 weren't 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.
