I am trying to figure out how to return the LIST INDEX INTEGER 11 from this list.
The numbers cannot be sorted to do it as they are unpredictable
Item 11 is the last non NULL value in that list. ie item 12 thru n are all NULL
The numbers will always appear before the NULLs meaning item 12 is the first occurance of NULL in the list.
And how do I generate the index numbers as a separate list to be sorted for example?
