History of SixtyPical

0.5-PRE

  • Added byte table type locations and indexed addressing (+ x, + y).
  • Integer literals may be given in hexadecimal.

0.4

  • Added repeat loops to the language, which can repeat until a flag is set (or not set), or which can repeat forever.
  • if not inverts the sense of the test.
  • Added explicitly-addressed memory locations.

0.3

  • Added external routine declarations.
  • Added ability to compile to 6502 machine code and output a PRG file.

0.2

A complete reboot of SixtyPical 0.1. The reference implementation was rewritten in Python. The language was much simplified. The aim was to get the analysis completely right before adding more sophisticated and useful features in future versions.

0.1

Initial inspired-but-messy version implemented in Haskell.
