Chapter 9 Writing Machine Language Instructions and Directive Statements
150 Instruction Statement Fields
9.2.3 Writing Operand Field
The operand field coding is determined by the machine language instruction or directive in the
operation field. Refer to the "Instruction Manual" for details on coding machine language instructions.
Coding rules
Operands are written with expressions and reserved words (register names, etc.).
Operands cannot include spaces, except for character constants and string constants.
When two operands are coded, they must be delimited by a comma (,).
