7. Other hints

7.1 Function keys

These are defined to be FUNCT + number key.

7.2 Passing arguments to the program

Command line arguments can be passed to main(). Since this is not supported by BASIC, the following syntax was chosen:

    CALL#500:REM ARG1 " ARG2 IS QUOTED" ARG3 "" ARG5

1. Arguments are separated by spaces.
2. Arguments may be quoted.
3. Leading and trailing spaces around an argument are ignored. Spaces within a quoted argument are allowed.
4. The first argument passed to main is the program name.
5. A maximum number of 10 arguments (including the program name) are supported.

7.3 Interrupts

The runtime for the Atmos 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.
