In short

What changes compared with Codoritmo's default profile:

No accents or ñ in variable names
Every statement must end with a semicolon
You can assign with = as well as <-
Arrays start at 0

All of its rules

Marked rules differ from Codoritmo's default profile; everything else behaves the same.

Variables

How they are declared and when they can be used.

Declare variables with Definir: Optional. You can use a variable without declaring it: its type comes from the first value you store in it.
Give a value before use: Not checked. It's still good practice to give every variable a value before using it.
Protected Para counter: You can change the counter inside the Para and keep using it after the loop ends.
Accents and ñ in namesDiffers from default: Not allowed in variable or subroutine names: write anio or posicion. Accented keywords such as Según still work.

Writing style

Punctuation, closing words and how values are assigned.

Semicolon at the endDiffers from default: Required. Every statement ends in ;, as in Escribir "Hola";. Lines that open or close a structure (Si, FinSi, FinPara) don't take one.
Relaxed syntax: Accepts handy variants: Fin Si as two words, optional Entonces and Hacer, Mientras Que and Desde in loops, and values in Escribir separated by spaces.
Assign with =Differs from default: Allowed: besides x <- 5 you can write x = 5. Inside a condition, = is still a comparison.

Operators and conditions

How comparisons are written and text is put together.

Word operators: You can write Y, O, NO and MOD (and, or, not, remainder) as well as their symbols &, |, ~ and %.
Plain-language conditions: Accepts conditions such as x Es Par (is even), x Es Mayor Que 5 (is greater than 5) or x Es Divisible Por 3.
Join text with +: Allowed: "Hola, " + nombre makes a single piece of text.

Arrays

Where indexes start and how the size is set.

First array indexDiffers from default: Arrays start at 0: after Dimension notas[3] the slots are notas[0], notas[1] and notas[2].
Array size from a variable: Allowed: you can read n and then write Dimension datos[n].
Resize arrays: You can change the size of an existing array with Redimensionar.

Loops and Segun

Which ways of repeating and choosing between cases it accepts.

Para Cada loop: Available: Para Cada nota de notas Hacer goes through every slot of an array.
Repetir … Mientras Que: A Repetir loop can end with Hasta Que condition (until) or Mientras Que condition (while).
Para counting down: If the start is greater than the end, Para counts down one by one even without Con Paso -1.
Segun with whole numbers: The value a Segun checks can also be text, with options such as "a".

Subroutines and text functions

Which extra tools you get to organise the program.

Your own subroutines and functions: You can write your own SubProceso or Funcion to split the program into parts.
Text functions: Available: Longitud, Subcadena, Mayusculas, Minusculas and Concatenar (length, substring, upper case, lower case, join).

An example that follows these rules

It works out the average of three marks. It's written for this profile, and the comments point out what changes compared with the default. We checked it with Codoritmo's interpreter using these same rules.
