NAME

callobj − draws an instance of an object

SPECIFICATION

C
callobj(obj)
Object obj;

FORTRAN
subroutine callob(obj)
integer*4 obj

Pascal
procedure callobj(obj: Object);

DESCRIPTION

callobj draws an instance of a previously defined object.  obj is the object identifier.  If callobj specifies an undefined object, the system ignores the routine. 

Global variables are not saved before a callobj.  For example, if a variable such as color is changed within an object, the change can affect the caller as well.  Use pushattributes and popattributes to preserve global variables across callobj routines.
