RPascal - Status

RPascal is still in its infancy. However, some smaller programs like prime number calculations or the Tower of Hanoi simulation have already been brought to work.



Working

• Variables and constants declarations
• Procedures, including call-by-reference and variable argument counts
• Blocks: for, if/else, while, repeat...until
• Recursion
• Some internal functions: read(ln), write(ln), clrscr, ...
• Some global variables: keypressed, ...

Missing

• Optimized saving of variables (using shallow/deep-copy techniques).
• Global vars like keypressed.
• More internal procedures.
• Arrays.
• Type definitions.
• File access.

Wishlist
IO port access, interrupt emulation (13h anyone), compiler backend suitable for PMSim execution (Motorola processors).
