Lesson 4 of 27
Control flow
You'll learn: Use
if, while, repeat..until, and numeric for with explicit steps.
if/elseif/else are statements, not expressions. while
checks before entering the body; repeat..until checks after,
so the body always runs at least once. Numeric for takes
start, stop[, step] — a negative step counts down. See
*Iteration* for the generic for.
Output
idle
Hit Run to execute.
Try it:
Rewrite the
while loop as a repeat..until. Then flip the initial value of i to 5 — while skips, repeat still runs once.
