Syntax

 VIRTUAL METHOD Val(
	cString
) AS USUAL CLIPPER

[ClipperCallingConventionAttribute(new string[] { ... })]
public virtual Usual Val(
	Usual cString = default
)

cString (Optional): Type: Usual
The string to convert. If the string cannot be converted to the appropriate value, this method returns NIL and sets FieldSpec:Status to indicate the reason for the failure (note that FieldSpec:Val() performs no other validations).

Type: Usual

Remarks

The FieldSpec:Val() method acts as the inverse of the FieldSpec:Transform() method, converting a transformed string back to its original value.
