Syntax
MemAdd(<Name of Memory Zone> , <Added Value> , <Return Value>)
<Name of Memory Zone>: Character string (with quotes)
Name of the memory zone, defined by MemCreate.
<Added Value>: Character string, integer or real
Value added into the memory zone (maximum size: 65521 bytes). This value corresponds to the sort argument used by MemSort. This value is returned by MemKeyVal.
<Return Value>: Character string (with quotes)
Value that will be returned by MemRetrieve or MemSetPosition.
Remarks

Existence of memory zone

The existence of the memory zone is not checked. If <Name of Memory Zone> does not exist, a WLanguage error occurs when MemAdd is run. To check the existence of a memory zone, use MemExist.

Sorting the elements

The element added into the memory zone is not sorted. MemSort must be used to sort the entire memory zone.
