Solutions: Procedures: Revisiting Squares

The Procedures in Pro-Bot are pre-named from Proc1 to Proc32.


1.  Let's write the program for the square and store it in a procedure called Proc1. Access the New Proc or Edit Proc options from the Menu button to access the procedures and  choose Proc1. Here's what Proc1 might look like:

// Remember that you would see Proc1 as the first line on the screen here, not Main.

   Rpt 4 [
   Fd 6
   Rt
   ]


// To run this Procedure, go back to Main by clicking on the Menu button. Call Proc1 from Main using the Proc key and the number 1 on the control pad. Then press Go and watch your Procedure execute.



2.   Here is one way to use Proc1 from the above program to draw the stack of squares.

     Rpt 3 [
     Proc 1
     Fd 6
     Rt
     Fd 6
     Lt
     ]





3.   To draw the coaches for the train using Proc1, you could use the following code:
   

    Rpt 3 [
    Proc 1
    Rt
    Fd 8
    Lt
    ]
