J Subscripts Attached to Double Integer Data
When a subscript is attached to double integer data, the value of I or J is added to the relay
number. For example, if I = 1, ML00000i will be the same as ML00001. ML00000j when J
= 0, and ML00000j when J = 1 will be as follows:
MW00002 MW00001
Higher-place word
MW00001
Lower-place word
MW00000
ML00000J when J = 0: ML00000
ML00000J when J = 1: ML00001

When a subscript is attached to double integer data, the value of I or J is added to the relay
number. For example, if I = 1, MF00000i will be the same as MF00001. MF00000j when J =
0, and MF00000j when J = 1 will be as follows:
MW00002 MW00001

J Programming Example Using Subscripts
The programming code shown in Figure 3.16 sets the sum of 100 registers from MW00100
to MW00199 in MW00200 using subscript J.
00000
FOR J = 00000 to 00099 by 00001
MW00200 + MW00100j
FEND
MW00200
MW00200
