If the conditions contain multiple operators, they are evaluated in the order that
you list them in the conditional statements table.
Table 11–3
The condition (pop=1)&(count_in=0) is higher in the table than the condition
(push=1)&(count_in=250), therefore it has higher priority.
The condition (pop=1)&(count_in!=0) has the next highest priority and the
condition (push=1)&(count_in=250) has the lowest priority.
