SAX 6.0 introduces new glyphs: "@" and "~", for the "from" and "merge" primitives currently denoted by " { " and "}". The new glyphs are a first step towards reclaiming " { " and " } " for reuse in control structure and direct definition (dynamic function) facilities that are planned for future releases of SAX. In SAX 6.0, the "old" glyphs for "from" and "merge" continue to be supported. To assist in their location and removal, a SAX start-up parameter has been added that enables tracing of their use. B APL Graphics Dump --by Walt.Miehoff Vestal, New York Transformations 2: Viewing NTHE LASTAPL GKAPHICSDUMr, I discussed the elementary transformations--magnification,translation, and rotation-and key properties of transformations in general. In this column, I'll continue with the thread developed last time, but this time my focus will be on viewing rather than modeling or model manipulation. In particular, we'll continue to exploit the pay-offthatresults from transformation associafivity:We can premultiply transformation matrixes, forming a composite matrix, and then perform the composite transformation on our objecCs coordinates. Documentation The SAX 6.0 Documentation Set is approximately 700 pages in size, and consists of a Language Guide, a System Guide, and a Handbook.
