Nested arrays and operations on nested arrays follow IBM APL2 conventions. <br /> Most primitive functions are no longer subject to the limit of 2 billion elements per simple array that existed in earlier 64-bit versions.<br /> <br /> Although APL applications tend to have a numerical focus, APL is also a terrific language for connecting things together; massaging, cleaning and redistributing data for use by APL code or indeed applications written in other languages. An important missing link has been integrated support for regular expressions. &ldquo;Regex&rsquo;s&rdquo; have become a tool that most young computer scientists, software engineers or hackers pretty much take for granted and miss when they move to APL.";
