Common mistake

Use Para when you know how many rounds; Mientras when it depends on something that happens inside.

In a flowchart

This is how it appears in a flowchart, with the same shapes Codoritmo draws.

Para i ← 1 Hasta 5…
In the flowchart. Flowchart: a Para loop hexagon reading "Para i ← 1 Hasta 5", the body below it and an arrow back to the hexagon on every pass.
