Details

If a radio box has been assigned a character value in the Value on Selection window, the _getValue method causes a program halt. Use the _getText method to return the value of a radio box that has a character value.

Example

_getValue returns the value of the active station in RBOX1 and assigns it to the variable VALUE. Each station in RBOX1 represents a different number of guests at a dinner party.

    call notify('rbox1','_get_value_',value);
    _msg_='You have made reservations for ' 
           || value || ' guests.';
