iCtr = 8
and currently it has 4 columns ( iCtr/2), if iCtr =10 then it would have 5 columns (iCtr/2)
and iCtr would always be even no.

Hi,
Here is the C code for you.
Justin
----------------------------------------------------

#include <stdio.h>

#define iCtr      8

void main(void)
{

int   counters[iCtr], temp;
int   i, round;
for (i=0;i<iCtr;i++)
counters[i] = i+1;
for (round=1;round<=iCtr;round++) {
printf("\nround: %d",round);
for (i=0;i<iCtr/2;i++)
printf("\n%d   %d",counters[i], counters[iCtr-i-1]);
temp = counters[iCtr-1];
for (i=1;i<iCtr-1;i++)
counters[iCtr-i] = counters[iCtr-i-1];
counters[1] = temp;
}
}

Sorry but I am not familar with vb/vb script.
Just let you know how I do.

initial (1st round)
[1][2][3][4] [5][6][7][8]

for each round, repeat (1) ~ (3):
(1) Save the last element.
temp = counters[iCtr-1];

now, temp=8.

(2) Shift the array to right except the first element.

[1][2][2][3] [4][5][6][7]

(3) Put temp to the second element.
counters[1] = temp;

[1][8][2][3] [4][5][6][7]
This is the result of 2nd round

'Place this code at appropriate place this is useful for the first round
' Maxcounter can be changed to 10,12 or what ever depending on the need

Dim i, limit As Integer
maxCounter = 8
limit = (maxCounter / 2) - 1
TextBox1.Text = " "
For i = 0 To limit
arrayNumbers(i) = i + 1
TextBox1.Text = TextBox1.Text & " " & arrayNumbers(i)

Next

For i = maxCounter - 1 To limit + 1 Step -1
arrayNumbers(i) = i + 1
TextBox1.Text = TextBox1.Text & " " & arrayNumbers(i)
Next
' Place this code at appropriate place, this will be calling the iterations for subsequent rounds

Dim i, j As Integer
For i = 1 To maxCounter - 1
moveArray(arrayNumbers, maxCounter)
Next

Private Sub moveArray(ByRef array() As Integer, ByVal maxElement As Integer)
' This function moves all the array elements from 2nd position to the last but one
' to the next position and the last element is placed as the second element
Dim lastNumber, i As Integer
lastNumber = array(maxElement - 1)
For i = maxElement - 2 To 1 Step -1
array(i + 1) = array(i)
Next
arrayNumbers(1) = lastNumber
End Sub
