Operand Format
The 34000 assembler differentiates syntactically between
register operands and
memory operands.
In certain contexts, only a memory operand can be used.
In particular:
- The operand of a jump or branch instruction must be a memory operand.
- The operand of a push effective address (pea) instruction must be a
memory operand.
- The first operand of a load effective address instruction (lea) must be
a memory operand.
In addition, the first operand of a link instruction must be an address
register name.
