Brackets

The THEN and ELSE are brackets that show the true branch of the structure. The ELSE and END IF are brackets that show the false branch of the structure.

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

Without any control structure affecting them, statements execute in sequential order. Brackets are needed only for loops and two-way decisions, where the normal sequential execution is altered.
