If you want something to happen five times, it usually works to put it inside a counting loop.

Line Printer as a Loop Body

Here is a counting loop that executes its body five times:

' Do the loop body five times
FOR LINE = 1 TO 5

  ' loop body

NEXT LINE
'
END

And here is a section of code that prints a row of ten stars.

' Print NUM stars in a row
LET NUM = 10
PRINT
FOR STARS = 1 TO NUM
  PRINT "*";
NEXT STARS

Fit the two pieces together so that five rows of ten stars are printed.
