N_NDX( [ <nIndex> ] )


Parameters

<nIndex>
Ordinal number (1-15) of index file open in the currently selected work 
area.


Returns

If the function is called with no argument, it returns the number 
(numeric data type) of index files open in the currently selected work 
area. If no index files are open, it returns zero.

If the function is called with a numeric argument, n, it returns the 
name (character data type) of the nth index file open in the current 
area. If no index files are open, or if n is greater than the number 
open, the function returns a null string.


Description

N_NDX(<nIndex>) works similarly to the dBase NDX() function. The number 
<nIndex> refers to the order in which index files were open, not the 
current SET ORDER.


Example

USE Customer INDEX Custno, Custname
? N_NDX()
2

? N_NDX(1)
CUSTNO.NTX
? N_NDX(3)
<null string>
