Logical operators Y, O, NO in PSeInt: examples

10 examples

How it works

Logical operators combine conditions. Y (and) is true only if both conditions are; O (or) if at least one is; NO (not) flips the result. They can also be written as &&, || and ~.

Y checks ranges: edad >= 13 Y edad <= 19. O accepts several answers: letra = "y" O letra = "Y". Use parentheses to make clear what is evaluated first.

A Logico variable holds true or false directly, like encontrado (found) or terminado (done). Mientras NO encontrado Hacer then reads almost like a sentence.

Short example
