  • 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! 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.

  • GFX: PEEK fetched bitmap pixels from ROM instead of RAM
  • V did not compile in DECIMAL mode.
