The control instructions include all privileged
instructions, except the input/ output instructions,
which are described in Chapter 12, "Input/Output
Operations. "
Privileged instructions may be executed only
when the CPU is in the supervisor state. An
attempt to execute a privileged instruction in the
problem state generates a privileged-operation
exception.
The control instructions and their mnemonics,
formats, and operation codes are listed in the figure

"Control Instructions." The figure also indicates
when the condition code is set and the exceptional
conditions in operand designations, data, or results
that cause a program interruption.
Note: In the detailed descriptions of the individual
instructions, the mnemonic and the symbolic
operand designation for the assembler language are
shown with each instruction. For LOAD PSw, for
example, LPSW is the mnemonic and D
2
(B;JJ the
operand designation.
