7. Other hints

7.1 Passing arguments to the program

Command line argument passing is currently not supported for the Commodore 510.

7.2 Program return code

The program return code (signed char) is passed back to BASIC by use of the ST variable.

7.3 Interrupt handlers

The runtime for the Commodore 510 uses routines marked as .INTERRUPTOR for interrupt handlers. Such routines must be written as simple machine language subroutines and will be called automatically by the interrupt handler code when they are linked into a program. See the discussion of the .CONDES feature in the assembler manual.
