Function
Interlocks all outputs between IL(002) and ILC(003)
when the execution condition for IL(002) is OFF.
IL(002) and ILC(003) are normally used in pairs.

execution
of the program
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.
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 inter-
locked. 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 differentia-
tion condition of the instruction was established.
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 inter-
locked.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 differ-
entiation condition of the instruction was established.
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 cor-
responding MILC(519) with the same interlock number
are interlocked when the execution condition for
MILH(517)/MILR(518) is OFF.
When the execution condition for JMP(004) is OFF,
program execution jumps directly to the first
JME(005) in the program with the same jump
number. JMP(004) and JME(005) are used in pairs.
