Add possibility to retrieve current number of filled elements in array with dim(*auto/*var)

Please add the number of filled elements in a varying dimension array. Currently we can set the allocated number with %elem(array: *alloc) = number. This says something about the memory being allocated as far as I understand.

If you then use 

for i 1 to %elem(array: *alloc) 

it will probably not end correctly as the assignment of allocated elements is not resulting in a hard number of elements but appears to do a "at least" this number of elements.

This means we still need to store the number of actual filled elements.


I would like a %elem(array: *filled) to retrieve the number of filled elements so we don't need to store the number ourselves.

    This functionality is already available.

    The simple form of %ELEM with just the array name, %ELEM(array), returns the current number of elements.

    for i = 1 to %elem(array);
