AMS 1.01 or higher | estack.h

unsigned short remaining_element_count (CESI start_ptr);

Returns number of elements remaining.

remaining_element_count counts how many expressions are stored on the expressions stack below the expression pointed to by ptr (including this one). END_TAG is treated as the terminator, so eventual expressions below END_TAG are not counted. So, if ptr points to an element of the list, remaining_element_count returns the number of elements in the list starting from this element up to the end of the list.
remaining_element_count works using repeated calling next_expression_index and increasing a counter until END_TAG is reached.
