• Changed REFILL to Forth standard behavior: Fill the input buffer from the input source, returning true if successful.
• #> (the pictured numeric output string buffer) now uses its own buffer, separate from HERE.
• Do not print "ok" while compiling. Makes it easier to re-enter multi-line word definitions in interpreter.
• Moved tests to a separate disk (tests.d64).
• gfx: Renamed ERASE to PEN.

v4.0.0

Changed

• OPEN/CHKIN/CHKOUT no longer return a file number.

• Moved and shrunk PAD area.
• Optimized * / EXIT C! C@ 0=
• Data stack effects of :/;/:NONAME/DEFINE. Starting with 2.0.0, :/:NONAME/DEFINE would put a value on the data stack, to be later consumed by ;. This is no longer the case.

Fixed

• LOADB/SAVEB could change active device.
• IOABORT did not print all error messages.
• REFILL would not properly switch back to keyboard after EOF.
• Cartridge initialization for Ultimate64.

v3.0.0

[3.0.0] - 2021-05-14

Changed

• Dictionary restructured, now header and code data are split.
• Header data is not a linked list, and grows downward from $9fff. Record structure: len_flags | str | xt
• LATEST changed from VARIABLE to VALUE
• V internal words hidden, BUFSTART no longer variable, fixed at $7000.
• Restore key is clean NMI, Run/Stop Restore to QUIT

• Turn-key operation utilities in TURNKEY:
• SAVE-PACK packs the dictionary together before saving, which unpacks at runtime.
• SAVE-PRG removes the dictionary and saves the program
• TOP returns the address of the last byte of the header structure. The value at this address will always be 0.
• TOP! can be used to specify the position of header data.
• HIDE removes a word from the word list, while leaving its definition in place.
• DEFINE assigns HERE to a word in the word list and begins compilation.
• DEFCODE does the same as DEFINE, but begins a CODE: segment instead.
