There are three main types of loops for QBasic. The loops are the While, Do Loop, and For loop. This tutorial will show the For loop.

Warning
Make sure that the loop has a condition that will end the loop. If there is not a condition to end the loop, the computer will be sent through an infinite loop. Sometimes, using CTRL BREAK (QBasic 1.1) can end the infinite loop.

For Loop Syntax
FOR counter = start TO end [STEP]
  [Statement Block]
NEXT counter
