This function is used to compare two text strings interpreted as date values. The source string may be a track's field or a named variable. The compare against field can be a specified text pattern, the contents of a named variable or the contents of a track's variable field. Note that when a value does not start with a valid date, it will be treated as zero.
When specifying named variables or a text pattern you may use any of the escape sequences described in Escape Sequences.
If you specify a result of Set, the action's test state will be set to True or False depending on the result of the test. If you specify a result of And, the action's test state will be set to false if the result of the test is false. If you specify result of Or, the action's test state will be set to true is the result of the test is true.
In stepwise execution mode the following holds: If the source is a named variable, the compare function is only performed once. If the source is a not a named variable the compare function is interpreted as for all files unless the Any option is selected.
