APLX for MacOS is now available as a native Intel binary, providing substantially higher performance for the new Intel-based range of Apple Macintosh systems. This has required a fairly large rework of the interpreter, and we would like to thank all our beta testers who have been helping us ensure the changeover is smooth. We strongly recommend any customers running APLX on an Intel-based Macintosh to upgrade to the new version. Not only is performance much better, but also Apples Rosetta PowerPC emulation software has a number of bugs in its emulation of floating-point instructions, and these can affect results when running the PowerPC version of APLX on Intel systems.
Meanwhile, at the Array Languages Day hosted by Dyalog in Helsingør in October, Richard Nabavi of MicroAPL previewed some of the new features planned for APLX Version 4, which will be available next year. These include new object-oriented extensions to the APLX language, and the ability to use classes written in a variety of other languages including C# (and other .Net languages), Java, and Ruby.
