callob(3G)callob(3G)NAMEcallob - 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.
DESCRIPTIONcallob 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.
