Answer:

The control statments (which implement a loop control structure) are highlighted in red:

LET COUNT = 1
'
DO WHILE COUNT <= 10
  PRINT "Count is now", COUNT
  LET COUNT = COUNT + 1
LOOP
PRINT "Done with the loop"
'
END

Indenting

A control structure controls the order in which statements are executed. The statements being controlled are contained inside some statements that bracket them. In the above example, the statements that are being controlled (called the body of the loop) are contained inside the DO and the LOOP. It is helpful for humans to use indenting to show which statements are being controlled. Here is another example:

PRINT "Enter the hour of the day 0-23"
INPUT HOUR
IF HOUR < 12 THEN
  PRINT "Good Morning"
ELSE
  PRINT "Good Day"
END IF
END
