Zeno programming language
Zeno (after 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 mantained 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
