callob(3G)

NAME
     callob - draws an instance of an object

FORTRAN 77 SPECIFICATION
     subroutine callob(obj)
     integer*4 obj

PARAMETERS
     obj   expects the object identifier of the object that you want to draw.

DESCRIPTION
     callob draws an instance of a previously defined object. If callob
     specifies an undefined object, the system ignores the routine.

     Global state attributes are not saved before a call to callob. Thus, if
     you change a variable within an object, such as color, the change can
     affect the caller as well.  Use pushat and popatt to preserve global
     state attributes across callob calls.

     Likewise, the object may execute transformations that change the matrix
     stack, so you may want to use pushma and popmat to restore the state of
     the matrix stack.
