INDEX.IS_VALID Function

Syntax

Result_Flag as L = Is_Valid()

Description

Is the current index valid.

Discussion

The .IS_VALID() method scans the records that qualify for the index and checks that there is a corresponding index entry for each. The method returns .T. (TRUE) if the current index is valid; otherwise, it returns .F. (FALSE).

Example

dim t as P
dim i as P
t = table.open("customer")
i = t.index_primary_put("Lastname")
? i.is_valid()
= .T.
