Remarks

Sorting the memory zone

The sorts performed by MemSort are taken into account during the call to MemLast.
If no sort was requested by MemSort, MemLast returns the value of the last element added by MemAdd.

Existence of memory zone

The existence of the memory zone is not checked.
If the specified memory zone does not exist, a WLanguage error occurs when MemLast is used.
To check the existence of a memory zone, use MemExist.
