## Exists Test

The purpose of this function is to test if one or more fields exist (are non empty) or do not exist (are empty). Based on the result of the test the action test state will be set.

The result of the test will be true if at least one field matches the desired condition. If no fields match the desired condition, the result of the test will be false.

The function stops in stepwise mode if any selected file meets the test criteria.

If the results mode is Set, the result will be assigned to the action test state. If the results mode is And, the result will be ANDed to the action test state's value prior to the start of the statement. If the results mode is OR. the result will be ORed to the action test state's value prior to the start of the statement. In the case of a results mode of AND or OR, the test is only performed if meaningful.
