For example if you wished to perform some action on holidays (such as, shading the textbox's background) you would write something like this:
bRESULT = HolidayOfList('a', n_TokenDate)
Then, in the script's macros options resulting actions dialog, you would set replacement actions in the TRUE and FALSE tabs corresponding to the 2 possible values of bRESULT at the end of the macro, as shown below.
If you do not set a value for bRESULT, it is assumed to be false.
