PRB: OptionButtons Do Not Hold Logical Values

• Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0

SYMPTOMS

In Visual FoxPro 5, it was possible to set OptionButtons to have logical values instead of numeric. However, in Visual FoxPro 6, this behavior changed. While the buttons can be set to logical values, clicking on a button will cause the button's value property to be reset to numeric.

CAUSE

OptionButtons should only have numeric values, even if the interface allows them to be set differently.

STATUS

This behavior is by design.
