Looping

`DO` loops can only be used in script files. `DO` loops must be terminated with `ENDDO`. The range of the `DO` loop can be any expression resulting in a vector. The loop will execute a number of times equal to the length of the loop range vector, with the loop variable taking on the values of each element of the loop range vector. Nested loops are allowed. The looping variable is created as a scalar variable.

Example

The variable `j` below will be made into a scalar:

     ...         !
     DO j = x    ! x must be a vector, loop will execute len(x) times with
      ...        ! j successively taking on the value of each element of x
     ENDDO       !
     ...         !

Example

     ...              !
     DO I = [2:20:4]  ! the loop will execute 5 times
      ...             !
     ENDDO            !
     ...              !

Example

     ...
     X = [1;3;5;7;9;10;12;14]
     DO I = X^2  ! the loop will execute LEN(X)=8 times with
      ...        ! I taking on the values [1;9;25;49;81;100;144;196]
     ENDDO
     ...
