در دستورالعمل های ستاره می توان از برنامه های زیر نیز استفاده کرد:

1)For i = 1 To 4

 For j = 1 To i

  For k = (i * j) To 3

  Print " ";

  Next k

 Print "**";

 Next j

Print

Next i       

2)For i = 1 To 8 Step 2

  For k = 4 - (i / 2) To 1 Step -1

  Print " ";

  Next k

  For j = 1 To i

 Print "**";

 Next j

Print

Next i
