Loops

Learn how to repeat actions using loops

While loop

A WHILE loop runs as long as the condition is true.

X = 0
WHILE X < 5
  PRINT X
  X = X + 1
END

Sum from 1 to N

Calculate a running total and watch it change in the debugger.

N = 5
SUM = 0
X = 1

WHILE X <= N
  SUM = SUM + X
  X = X + 1
END

PRINT SUM

Countdown

Loop backwards from a number to zero.

X = 5
WHILE X >= 0
  PRINT X
  X = X - 1
END

Loop with input

Ask the user for input multiple times.

X = 0
WHILE X < 3
  INPUT A
  PRINT A
  X = X + 1
END
