For var := start To end Do command For var := start To end [Do] commands Next
Counting loop. The variable var, which must have been declared before, starts at start and counts up in steps of 1 until it reaches end. For each value, the command (or command list) is executed.
For example,
For i:=1 To 5 Do Print i
prints the numbers 1, 2, 3, 4 and 5.
