v4.0.0

[jkotlinski]

Changed

• OPEN/CHKIN/CHKOUT no longer return a file number.
• IOABORT no longer accepts a file number.
• INCLUDED now prints error message on failed OPEN.
• REQUIRED now aborts with "too many" if 16 files are already INCLUDED.
• V: Moved text buffer to $a000-$cbff.
• 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.
• Press RESTORE to QUIT. (v3.0.0 inadvertedly changed this to RUN/STOP+RESTORE.)
• V: Abort when loading a text file bigger than 44 blocks = 11,176 bytes.
• V: Inserting SHIFT+RETURN would make things weird.
• V: Improved I/O error handling.
• sid-demo broke in 2.0.0.
• :NONAME did not work with RECURSE.
• Rewrote UD/MOD in assembly

Removed

• BYE, SEE, XT>
• HIDDEN word header flag.
