is the output element name that depends on the directive used as shown in the
following table:
Directive ro
$REL (or absence of $DEF,
$OBJ, or $SOR)
Relocatable output element name
$DEF Omnibus output element name
$OBJ Object module output element name
$SOR Symbolic output element name
If ro is omitted, the assumed name is NAME$ in TPF$.
is the source output element name.
Commas and spaces are significant in the processor call statement since they identify
the different components. Therefore, they must be included whenever a preceding entry
is omitted.
Table 2-1. MASM Options
Option Description
A Performs additional address checking to ensure base register specification on
extended mode instructions with a base register selector (b-field) and $EQUFs. A
symbol with a $EQUF must have a base register selector available when used, but it is
not required when the symbol is defined.
If no base register is provided by the $EQUF and B0 is forced on the resulting
instruction due to a $USE directive (only applies to B0 on the $USE), an A flag is
generated since it is assumed that B0 was established as a default and may not be
desirable. If you are not using this technique, the A flag can be ignored by turning off
the A option after verifying that B0 was the desired resultant base register.
B Uses batch format in demand mode (assumed if @BRKPT PRINT$ is active when
MASM is initiated).
