Private Sub Command1_Click()
For i = 1 To 7 Step 2
s = For j = 1 To 7 - i Step 2
s = s &
Next j m = For k = 1 To i
m = m & i Next k s = s & m Print s
Next i If i = 9 Then
For i = 5 To 1 Step -2
s = For j = 7 - i To 1 Step -2
s = s &
Next j m = For k = i To 1 Step -1
m = m & i Next k s = s & m Print s
Next i End IfEnd Sub
