0013 - Clear a Variable
Description:
How to clear a variable's answer.
How to clear a variable's answer.
Use SET Variable TO UNANSWERED. This works for all types of variables. For example:
SET TextVar TO UNANSWERED SET DateVar TO UNANSWERED SET NumVar TO UNANSWERED SET TFVar TO UNANSWERED SET MultChoice TO UNANSWERED
For text variables, you can also use SET TextVar TO "".
Caveat: There is a temptation to want to use CLEAR to remove a variable's answer. Contrary to intuition, CLEAR does not clear a variable. Rather, it clears out all of a multiple choice variable's options. Careful!
