The following two operators may occasionlly be needed. The \b operator
can be simulated in other ways but is useful to have. Its function is to break
one level back. Normally it is used within the body of a loop to break out of
the loop on certain conditions (as an addition to the standard loop condition
in while loops). The \e operator exits the entire equate expression all
the way back to where it was initially called from within a text body or in a
filter evaluation. Neither of these operators will alter the stack. For example,
the fragment below searches all the records for a matching field and returns
the record number of the record the field matched.
%%EQUATE FIND 1>>N(%NAME"Smith"=?\b:++N>>N;)<<N
