Processing rules on fields in a map in Natural

How do I code a processing rule on a map for an array - specifically concerning the index.
If I manually change the index on each occurrence of the array - all the occurrences changes similarly.
Example
Rule ________________________________ Array STRT-MIN

                                 > + Rank 0    S 1    L 1     Report Mode

ALL …+…10…+…+…+…30…+…+…+…50…+…+…+…70.
0010 IF & (1) > 59 THEN REINPUT ‘MAX MINUTES 59’ MARK *& (1)

Hi Bertus,
Well, I used to do such things as follows (just an example)
DEFINE DATA LOCAL
1 #I (I4)
END-DEFINE
FOR #I = 1 TO 3
IF & (#I) NOT = ‘22’
REINPUT ‘22 is required’ MARK *&(#I)
END-IF
END-FOR
Hope this would help you :slight_smile:
