choose case key
   case keyenter!
       if this.getcolumn()<>long(this.object.datawindow.column.count) then
           send(handle(this) ,256,9,long(1,1))
       else
           //cb_save.setfocus()
       end if
       return 1
   case
   Keypageup! ,Keypageup! ,Keypagedown! ,Keyend! ,Keyhome! ,Keyleftarrow! ,
       KeyupArrow! ,KeyrightArrow! ,KeydownArrow!

       return 1
   case keyescape!
       close(parent)
end choose    

这个程序一直显示case
   Keypageup! ,Keypageup! ,Keypagedown! ,Keyend! ,Keyhome! ,Keyleftarrow! ,
       KeyupArrow! ,KeyrightArrow! ,KeydownArrow!

语句系统错误!!
大家能帮助解决一下不,谢谢!!
