LM80C firmware R3.7
Lot of improvements:
- Added HELP command to automatically list the line where a program error has occurred;
- added modulo operator '%' to make modulus operations between integers (returns the remainder of an integer division);
- added integer division operator '#' (return the integer part of a division);
- added support for function keys into firmware;
- added KEY command to manage function keys: it is now possible to print the current functions and assign new functions to the keys;
- revised PAUSE code: it is now possible to break the delay with the "RUN STOP" key;
- better error management when in graphic modes: now if an error occurs in G2 and G3 modes, the BASIC interpreter returns into G1 mode; same behavior if an error occurs in direct mode while in graphics modes;
- pressing the "RUN STOP" key while in direct mode and in graphics modes leads the interpreter to return to G1 mode.
