OPT

Assembler Directives - OPT

OPT

The OPT directive is used to set assemblers options from within the source file. The OPT directive is followed by one of the following options:

MEX Macro EXpand. The following macro calls will be expanded by the assembler.

NOMEX No Macro EXpand. The following macro calls will NOT be expanded by the assembler.

SEX
Structured EXpand. The following structured assembly statements will be expanded by the assembler.

NOSEX No Structured EXpand. The following structured assembly statements will NOT be expanded by the assembler.

WAR Enables display of warning messages during assembly.

NOWAR Disables display of warning messages during assembly.

BIT Enables assembly of bit field instructions. Only 68000 addressing modes are supported. Adds *[sim68k]bitfield to .L68 file which automatically enables bit field support in Sim68K. Note! There is not a matching NOBIT option because there is no way to selectively disable bit field support in Sim68K during program execution.
