OPTION

v3.1

The OPTION directive sets various compilation options. Most of these options can be set from the command line as well. The OPTION directive gets higher priority than command line options.

Syntax

OPTION <option_name> [= <value>]

Note

OPTION directives must precede any other commands in the program.

Examples

To set the target machine, use:

OPTION TARGET = "c128"

Accepted values are:

  • "c64" (Commodore-64)
  • "vic20" (Commodore VIC-20 unexpanded)
  • "vic20_3k" (Commodore VIC-20 with 3k RAM expansion)
  • "vic20_8k" (Commodore VIC-20 with 8k RAM expansion)
  • "cplus4" (Commodore Plus/4)
  • "c16" (Commodore-16)
  • "c128" (Commodore-128)
  • "pet2001" (Commodore PET2001)
  • "pet3008" (Commodore PET3000 series with 8k RAM)
  • "pet3016" (Commodore PET3000 series with 16k RAM)
  • "pet3032" (Commodore PET3000 series with 32k RAM)
  • "pet4016" (Commodore PET4000 series with 16k RAM)
  • "pet4032" (Commodore PET4000 series with 32k RAM)
  • "pet8032" (Commodore PET8000 series)

To disable the BASIC loader, use:

OPTION NOBASICLOADER

If the above option is set, the compiled program will be a bare machine language binary that you can only run using the SYS command from CBM BASIC.

To set the start address of the program, use:

OPTION STARTADDRESS = $C000

This really makes sense when used together with OPTION NOBASICLOADER.

To enable inline data injection, use:

OPTION INLINEDATA

See DATA for additional details.

To use Fast Interrupts, use

OPTION FASTINTERRUPT

See Interrupts for more information.
