END END --- Indicates the end of a program.
NO OPERA-
TION
NOP --- --- This instruction has no function. (No processing is performed for
NOP(000).)
INTERLOCK IL --- Interlocks all outputs between IL(002) and ILC(003) when the exe-
cution condition for IL(002) is OFF. IL(002) and ILC(003) are nor-
mally used in pairs.
INTERLOCK
CLEAR
ILC --- All outputs between IL(002) and ILC(003) are interlocked when
the execution condition for IL(002) is OFF. IL(002) and ILC(003)
are normally used in pairs.
MULTI-INTER-
LOCK DIFFER-
ENTIATION
HOLD
MILH --- When the execution condition for MILH(517) is OFF, the outputs
for all instructions between that MILH(517) instruction and the next
MILC(519) instruction are interlocked. MILH(517) and MILC(519)
are used as a pair.
MILH(517)/MILC(519) interlocks can be nested (e.g., MILH(517)-
MILH(517)-MILC(519)-MILC(519)).
If there is a differentiated instruction (DIFU, DIFD, or instruction
with a @ or % prefix) between MILH(517) and the corresponding
MILC(519), that instruction will be executed after the interlock is
cleared if the differentiation condition of the instruction was estab-
lished.

ENTIATION
RELEASE
MILR --- When the execution condition for MILR(518) is OFF, the outputs
for all instructions between that MILR(518) instruction and the next
MILC(519) instruction are interlocked.MILR(518) and MILC(519)
are used as a pair.
MILR(518)/MILC(519) interlocks can be nested (e.g., MILR(518)-
MILR(518)-MILC(519)-MILC(519)).
If there is a differentiated instruction (DIFU, DIFD, or instruction
with a @ or % prefix) between MILR(518) and the corresponding
MILC(519), that instruction will not be executed after the interlock
is cleared even if the differentiation condition of the instruction was
established.
MULTI-INTER-
LOCK CLEAR
MILC --- Clears an interlock started by an MILH(517) or MILR(518) with the
same interlock number.
All outputs between MILH(517)/MILR(518) and the corresponding
MILC(519) with the same interlock number are interlocked when
the execution condition for MILH(517)/MILR(518) is OFF.
JUMP JMP --- When the execution condition for JMP(004) is OFF, program exe-
cution jumps directly to the first JME(005) in the program with the
same jump number. JMP(004) and JME(005) are used in pairs.
