               in a window within specified limits.

 Opcode:       61

 Syntax:       void objc_wchange ( OBJECT *ob_ctree, int16_t 
               ob_cobject, int16_t ob_cnewstate, GRECT *clip, int16_t 
               whandle );

 Description:  The call objc_wchange alters the display state of an 
               object in a window and, if necessary, redraws it. The 
               following apply:

                Parameter     Meaning

                ob_ctree      Address of the object tree
                ob_cobject    Index of the relevant object

                clip          Bounding clipping rectangle
                whandle       Window identifier

               objc_change (without a redraw) followed by objc_wdraw.

 Return value: An error has arisen only if the value 0 is returned.

 Availability: The function is available in MagiC as of Version 5.10.
