OrdKey Function

 FUNCTION OrdKey(
	uOrder,
	cIndexFile
) AS USUAL CLIPPER

[ClipperCallingConventionAttribute(new string[] { ... })]
public static Usual OrdKey(
	Usual uOrder = default,
	Usual cIndexFile = default
)

Parameters

uOrder (Optional)

Type: Usual
The name of the order whose key expression you want to obtain or a number representing its position in the order list.
Using the order name is the preferred method since the position may be difficult to determine using multiple-order index files. Invalid values are ignored.

cIndexFile (Optional)

Type: Usual
The name of an index file, including an optional drive and directory (no extension should be specified).
Use this argument with cOrder to remove ambiguity when there are two or more orders with the same name in different index files.
If cIndexFile is not open by the current process, a runtime error is raised.

Return Value
