<div>Hello Wolfgang,</div><div><br></div>Index is just like the index in an array. the value can be any from 0 to the array length. <div>for the previous example, the length is 1 so index can be either 0 or 1. but in the real case, the length can be an arbitrary number.</div>
<div><br></div><div>another question, there are 2 rules here, do both of them have to be applied?</div></blockquote><div><br>One creates and inserts the PatternConsumer which blocks repeated usage of the pair of EventB facts that have been successfully paired. Otherwise a sequence EventB:0, EventB:1, EventB:2 would fire 2 times.<br>
<br>If the positive condition is more complex, e.g., you need *all* index values 0,...,L-1 within 2m, then other conditions will be required (and that's what I meant with "more precisesly"). If any pair a,b from [0..L-1] will do, then the modified version (!=) should be OK.<br>
