Syntax
<Result> = MemRetrieve(<Name of memory zone> , <Subscript>)
<Result>: Character string
  • Return value of the specified element (defined by MemAdd or MemModify),
  • Empty string ("") if the specified element was not found.
<Name of memory zone>: Character string (with quotes)
Name of memory zone, defined by MemCreate.
<Subscript>: Integer

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 MemRetrieve is run.
To check the existence of a memory zone, use MemExist.

Positioning in the memory zone

MemRetrieve is not positioned on the element used. To position on the <Subscript> element, use MemSetPosition.
