做了一个子程序来调用，可是调用的时候误动作，请教各位老师，做子程序应该注意什么，

程序如下：
Network 1
LD SM0.0
LPS
MOVW LW0, LW10
-I LW2, LW10
AW>= LW10, +10
S L10.0, 1
LRD
AW<= LW10, -10
S L8.4, 1
LRD
AW= LW10, +0
R L8.3, 1
R L8.4, 1
LRD
LDW>= LW10, +20
OW<= LW10, -20
ALD
= L8.5
LRD
LPS
MOVW LW0, LW12
-I LW4, LW12
AW>= LW12, +10
S L8.6, 1
LPP
AW<= LW12, -10
S L8.7, 1
LRD
AW= LW12, +0
R L8.6, 1
R L8.7, 1
LRD
LDW>= LW12, +20
OW<= LW12, -20
ALD
= L9.0
LRD
LPS
MOVW LW0, LW14
-I LW6, LW14
AW>= LW14, +10
S L9.1, 1
LPP
AW<= LW14, -10
S L9.2, 1
LRD
AW= LW14, +0
R L9.1, 1
R L9.2, 1
LPP
LDW>= LW14, +20
OW<= LW14, -20
ALD
= L9.3
Network 2
LD L8.5
O L9.0
O L9.3
= L8.2
Network 3
LD L8.3
O L8.6
O L9.1
= L8.0
Network 4
LD L8.4
O L8.7
O L9.2
= L8.1
