1. Find event 2 "n" times after event 1, before event 3 occurs
This macro becomes true when it first finds a designated pattern 1, followed
by a selected number of occurrences of a designated pattern 2. In addition, if
a designated pattern 3 is seen anytime while the sequence is not yet true, the
sequence starts over.
If
patt2's "nth" occurrence is coincident with patt3,
patt2 takes precedence. It uses two internal sequence levels.
2. Find too few states between event 1 and event 2.
This macro becomes true when a designated pattern 1 is seen, followed by a
designated pattern 2, and with less than a selected number of states
occurring between the two patterns. It uses three internal sequence levels.
3. Find too many states between event 1 and event 2.
This macro becomes true when a designated pattern 1 is seen, followed by at
least a selected number of states, then followed by a designated pattern 2. It
uses two internal sequence levels.
