Small Basic: How to Create For Loops

How to create Loops. How to create Loops. How to create Loops.

Sometimes we need to do something a couple of times.

'do the following 3 times

   'move the tortoise 50 pixels

   'turn the tortoise 120 degrees

'repeat

This could be translated with some easy cut & pasting:

Tortise.Move(50)

Tortise.Turn(120)

Tortise.Move(50)

Tortise.Turn(120)

Tortise.Move(50)

Tortise.Turn(120)

But this quickly becomes tiresome. A better approach is to use the For Loop:

For i = 1 to 3

   Tortise.Move(50)

   Tortise.Turn(120)

EndFor

Notice that it seems to more closely follow the English:

'Do the following 6 times

...translates to:

For i = 1 to 6

and

'Repeat

becomes

EndFor
