CPU string
The instruction set can be specified in the source file with
the CPU pseudooperation. The string, delimited by quotes or
apostrophes, is scanned for a substring which selects which
instruction set is used. When the program is invoked, this
operation is performed on the name of the program, then the
-p optional arguement, if any, and then any CPU statements.
The last one selects which subset of the instructions the
assembler will accept. The instruction set can be changed
at any place in the source file.

DIRECT The instruction can use the direct
addressing mode. The expression
must have a value between 0 and 255
that is defined when the
instruction is processed in the
input pass.
EXTENDED The instruction can use the
extended (16 bit address) mode.
- 9 -
INDEXX The instruction can use the X
index.
INDEXY The instruction can use the Y
index.
INSTCMOS The instruction is in the CMOS and
ROCKWELL CMOS instruction sets.
INSTROCKWELL The instruction is in the ROCKWELL,
ROCKWELL CMOS, and R65c00/21
instruction sets.
INST21 The instruction is in the R65c00/21
instruction set.
A.2.4 _✓A_✓p_✓o_✓s_✓t_✓r_✓o_✓p_✓h_✓e_✓s The apostrophes in the syntax field are
a notation used for the parser generator and are not put in
the assembler source statement.

A.3.1 _✓T_✓o_✓p__✓E_✓x_✓p_✓r_✓e_✓s_✓s_✓i_✓o_✓n_✓s The syntax of some of the
instructions combined with the standard expression syntax
resulted in confusion whether an operand was an expression
surrounded by parenthesis, or a indexed reference. To get
around this, the expressions in these ambiguous cases were
restricted to those forms of expression that don't have
surrounding parenthesis at the top level. Subexpressions
may be parenthesized, but only if an operator seperates or
precedes the subexpression.
Example
lda 47h,y ; load absolute, y
lda +(47h),y ; load absolute, y
lda (47h),y ; load (indirect), y
lda ((47h)),y ; error
