Zeno (programming language)


Zeno 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 of boolean

program

var i, j : int

init_a % initialize array

for i := 2...floor do
for j := 2...floor do
a := false % mark as not prime
end for
end for
j := 0
for i := 2...N do % output results
if a then % is prime
put i : 6...
incr j
if = 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 := true
end for

end procedure
