can anyone change this to out put virtically:

function CreateVerticalV2 : array 1 .. 6 of int
var X : array 1 .. 6 of int
var found : boolean
X (1) := Rand.Int (2, 9)

for i : 2 .. 6
loop
X (i) := Rand.Int (2, 9)
found := false
for j : 1 .. i - 1
if X (i) = X (j) then
found := true
exit
end if
end for
exit when found = false
end loop
end for
result X
end CreateVerticalV2

Considering you're not outputting anything at all, it makes it kind of hard to see where you're going wrong. All your function does is return a value, assuming you're coding with good style, you'll be outputting in your main loop.

function CreateVerticalV2 : array 1 .. 6 of int % (no parameters needed)
var X : array 1 .. 6 of int
var found : boolean
X (1) := Rand.Int (2, 9) % pick any random for the first one

for i : 2 .. 6
loop
X (i) := Rand.Int (2, 9) % pick a random number
found := false % assume it hasn't been used before
for j : 1 .. i - 1 % check all previous numbers to see if a duplicate exists
if X (i) = X (j) then
found := true % bad - must try a new random
exit
end if
end for
exit when found = false
end loop
end for
result X
end CreateVerticalV2

% MAIN
var hN :array 1..6 of int
hN := CreateHorizontalV2
for i : 1 .. 6
put hN (i) : 3 ..
end for
put ""

here's your mainline:

Turing:

% MAIN
var hN :array 1..6 of int
hN := CreateHorizontalV2
for i : 1 .. 6
    put hN (i) : 3 ..
end for
put ""


and here's my version of your mainline:

Turing:

% MAIN
var hN :array 1..6 of int
hN := CreateVerticalV2
for i : 1 .. 6
    put hN (i) : 3
end for
put ""


What did I change to fix it? (We'll leave the fact that CreateHorizontalV2 was not declared out for now).
