VALUE

Description

The VALUE? command obtains the set-state of CHECKBOXes and RADIOBUTTONs. The set-state will be either "set" or "reset".

Syntax

#handle.ext "value? varName$"

Hints

Check-boxes and radio-buttons can be either set or reset (cleared). To have your program query the control for its state, issue the command

#handle.ext "value? varName$"

The variable varName$ will contain the value "set" or "reset". varName$ can be most any name you choose, but must be a string variable.
