This function is not defined in release 6.0. In earlier releases, Common Graphics provided generic drawing and related functions draw, erase, this function, graphics-fill, etc. which took instances of shape classes and drew them on or erased them from streams. It was determined that this capability was not, in fact, useful. All have been removed. See release-notes.htm for a complete list of removed classes and operators.
Common Graphics and IDE documentation is described in About Common Graphics and IDE documentation in cgide.htm.
