Description
List function; identifies the position (linear list) or property (property list) associated with the value specified by value
in the list specified by list
.
For values contained in the list more than once, only the first occurrence is displayed. The getOne
command returns the result 0 when the specified value is not in the list.

command.
Example
This statement identifies the position of the value 12 in the linear list Answers, which consists of [10, 12, 15, 22]:
put Answers.getOne(12)
The result is 2, because 12 is the second value in the list.

put Answers.getOne(12)
