Syntax
DELETE_INDEX IndexName
Description
This instruction destroys the index IndexName, to avoid updating it when the list (upon which the index is based) is modified.
The index is created once more when the READ_ELT or READ_F_ELT IndexName instruction is next issued.
Destruction allows you, for example to manage a list index only temporarily in a program, and to release the resources (memory) if this index is no longer used by other programs, but that the list is a parameter.
In all cases, all indexes for a list will be destroyed (and resources released) when the list is released by the source program that declared it.
Example
DELETE_INDEX MyIndex
