However, the magentaGO command is totally obsolete. In general any magentaGO SOMETHING is simply replaced by the equivalent command magentaSOMETHING: e.g. type magentaVIEW instead of magentaGO VIEW. magentaGO PLOT (or its variants magentaGO BIT, magentaGO NICE and magentaGO MAP) and magentaGO UVSHOW are replaced by the magentaSHOW command, which offers many more possibilities.
The capabilities given by the magentaINPUT [rgb]1,0,0MAPPING command have in general be replaced by the more flexible use of the question mark (magenta?, or magenta??, or even magenta???) as arguments to individual [rgb]1,0,0IMAGER commands. Most commands display their control parameters with such arguments.
Take a little time to browse through magentaHELP SHOW and magentaHELP VIEW to get familiar with [rgb]1,0,0IMAGER display capabilities.
