Control Structures

A control structure controls the order in which statements are executed. You have already seen all the control structures you need for even the largest of programs:

1. Sequential Execution
2. Loops
3. Choice

This chapter emphasizes sequential execution. The next chapter looks at the other two control structures. Here is a program from a previous chapter:

LET MILES = 200                             <—— executed first 
LET GALLONS = 10                            <—— executed second
PRINT MILES / GALLONS, "Miles per Gallon"   <—— executed third
END
