Differences between MILH(517) and MILR(518)

Differentiated instructions (DIFU, DIFD, or instructions with a @ or % prefix) operate differently in

interlocks created with MILH(517) and MILR(518).

The operation of differentiated instructions in an interlock created with MILH(517) is identical to the

operation in an interlock created with IL(002).

For details, refer to 3-5-5 MULTI-INTERLOCK DIFFERENTIATION HOLD, MULTI-INTERLOCK

DIFFERENTIATION RELEASE, and MULTI-INTERLOCK CLEAR: MILH(517), MILR(518), and

Do not combine interlocks created with different interlock instructions (IL-ILC, MILH-MILC, and MILR-

MILC). The interlocks may not operate properly if different interlock methods are used together. For

details on combining instructions, refer to 3-5-5 MULTI-INTERLOCK DIFFERENTIATION HOLD,

MULTI-INTERLOCK DIFFERENTIATION RELEASE, and MULTI-INTERLOCK CLEAR: MILH(517),

MILR(518), and MILC(519).

For example, an MILH(517) instruction cannot be inserted between IL(002) and IL(003).

Note The different interlocks (IL-ILC, MILH-MILC, and MILR-MILC) can be used together as long as the inter-

locked program sections do not overlap.

For example, all three interlock methods can be used without overlapping, as shown in the following

CS/CJ/NSJ Series Instructions Reference Manual (W474)

MILH(517) is in an interlocked area

between IL(002) and ILC.(003).

Different interlock methods can be

used as long as the interlocked

areas do not overlap.
