Syntax
MemModify(<Memory area> , <Modified Value> , <Return value> , <Subscript>)
<Memory area>: Character string
Name of the memory area, defined by MemCreate.
<Modified Value>: Character string, integer or real
Value that is modified in the memory area. This value corresponds to the sort argument used by MemSort. This value is returned by MemKeyVal.
<Return value>: Character string
Value returned by MemRetrieve or MemSetPosition.
<Subscript>: Integer
Index of the element to be modified. The index of an element is returned by MemCurrent or MemSeek.
Remarks

Existence of memory area

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

Sorting the elements

The element modified in the memory area is not sorted. To sort the entire memory area, use MemSort.
