For example, if all reaching definitions for the operands of some simple expression are outside of the loop, the expression can be moved out of the loop. Recent work by Moyen, Rubiano and Seiller uses data-flow dependence analysis [1] to detect not only invariant commands but larger code fragments such as an inner loop. The analysis also ...
It offered operating system commands within its environment: The 'new' command created an empty slate; Statements evaluated immediately; Statements could be programmed by preceding them with a line number; The 'list' command displayed the program; The 'run' command executed the program; However, the Basic syntax was too simple for large ...
var x1 = 0; // A global variable, because it is not in any function let x2 = 0; // Also global, this time because it is not in any block function f {var z = 'foxes', r = 'birds'; // 2 local variables m = 'fish'; // global, because it wasn't declared anywhere before function child {var r = 'monkeys'; // This variable is local and does not affect the "birds" r of the parent function. z ...
