| + | ==== Interpreter Info ==== | ||
| + | |||
| + | OF816 is a direct-threaded Forth with 32-bit cells and 8-bit characters. | ||

| + | * Providing the Core word set. | ||
| + | * Providing ''.('', ''.R'', ''0<>'', ''0>'', ''2>R'', ''2R@'', '':NONAME'', ''<>'', ''?DO'', ''AGAIN'', ''CASE'', ''COMPILE,'', ''ENDCASE'', ''ENDOF'', ''ERASE'', ''EXPECT'', ''FALSE'', ''HEX'', ''NIP'', ''PAD'', ''PARSE'', ''PICK'', ''REFILL'', ''RESTORE-INPUT'', ''ROLL'', ''SAVE-INPUT'', ''SOURCE-ID'', ''SPAN'', ''TO'', ''TRUE'', ''TUCK'', ''U.R'', ''U>'', ''UNUSED'', ''VALUE'', ''WITHIN'', ''[COMPILE]'', and ''\'' from the Core Extensions word set. | ||
| + | * Providing ''2CONSTANT'', ''D+'', ''D-'', ''D.R'', ''D>S'', ''DABS'', ''DNEGATE'', and ''2ROT'' from thge Double-Number word set. | ||
| + | * Providing the Exception word set. | ||
| + | * Providing the Facility word set. | ||
| + | * Providing Programming-Tools word set. | ||
| + | * Providing '';CODE'', ''AHEAD'', ''BYE'', ''CODE'', ''FORGET'', and ''STATE'' from the Programming-Tools Extensions word set. | ||
| + | * Providing the Search Order word set. | ||
| + | * Providing ''-TRAILING'', ''BLANK'', ''SEARCH'', and ''SLITERAL'' from the String word set. | ||
| + | |||
| + | === Console I/O === | ||
| + | |||
| + | At startup, it initializes the slot 3 Pascal I/O interface which, on a IIgs, is always going to be the built in text display. It sets up vectors for the input, output, and status calls. These calls are the only thing that happen in emulation mode after Forth is initialized. | ||
| + | |||
| + | === Data Space === | ||
| + | |||
| + | The data space is acquired from the Toolbox and is currently set at 32K and is allowed to cross bank boundaries. | ||
