22. Multiple REPEAT Filters

Description

How to use multiple FILTERs for a single REPEAT.

Code

Computation CombinedFilters-c:

FilterOne AND
FilterTwo AND
FilterThree

Use CombinedFilters-c as the filter
for your REPEAT, as so:

REPEAT RepeatedDialog
FILTER CombinedFilters-c
...
END REPEAT

Explanation

A filter is simply a computation variable that returns TRUE/FALSE. By creating a single computation, such as CombinedFilters-c above, that calls all of the desired filter computations, you can determine whether they are all TRUE or not. If they are all true, your combined filter computation will return TRUE. Otherwise it will return FALSE.
