Zeno (after pre-Socratic Greek philosopher Zeno of Elea) is an imperative procedural programming language designed to be easy to learn and user friendly. Zeno is generic in the sense that it contains most of the essential elements used in other languages to develop real applications. The Zeno Interpreter was designed for use in Windows 95 and later Microsoft operating systems. The interpreter comes with built-in debugging tools, a source code text editor, and an on-line language reference. Zeno was created by Stephen R. Schmitt and is maintained by Abecedarical Systems. Example: Sieve of Eratosthenes const N : int := 5000 var a : array[N] of boolean program var i, j : int init_a % initialize array for i := 2...floor ( N/2 ) do for j := 2...floor ( N/i ) do a[i*j] := false % mark as not prime end for end for j := 0 for i := 2...N do % output results if a[i] then % is prime put i : 6 ... incr j if (j mod 5) = 0 then % start new line put "" end if end if end for end program % initialize the array procedure init_a var i : int for i := 1...N do a[i] := true end for end procedure Sample output 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113 External links Home page Zeno 1.3 Website Procedural programming languages Educational programming languages Programming languages created in the 20th century
