Dependent USING domains

The domain of a dependent USING begins where the dependent USING instruction appears in the source module and continues until the end of the source module, except when:

• You end the domain of the corresponding ordinary USING by specifying the base register or registers from the ordinary USING instruction in a subsequent DROP instruction.
• You end the domain of the corresponding ordinary USING by specifying the same base register or registers from the ordinary USING instruction in a subsequent ordinary USING instruction.
• You end the domain of a labeled dependent USING by specifying the label of the labeled dependent USING in the operand of a subsequent DROP instruction.
