SYS/SYS
Called and execute a machine language subroutine at
the specified address
SYS address C64 mode
SYS address [,a] [,x] [,y] [,s] C128 mode
This statement performs a call to a machine code subroutine at
the given address in a memory configuration set up according to
the BANK command. Optionally, arguments a,x,y and s are
loaded into the accumulator, x, y and status registers,
respectively before the subroutine is called.
The address range is 0 to 65535. The program begins executing
the machine-language program starting at that memory location.
Also see the BANK command.
