In short

What changes compared with Codoritmo's default profile:

No accents or ñ in variable names
No conditions like Es Par: comparisons use operators
Arrays start at 0
Repetir only ends with Hasta Que
Counting down needs Con Paso -1
Segun only works with whole numbers

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 end: Optional. You can end statements with ; or leave it out.
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 =: Not allowed: you assign only with <-; = is only for comparing.

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 conditionsDiffers from default: Doesn't accept them: write the comparison with operators, such as x MOD 2 = 0 or x > 5.
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 QueDiffers from default: A Repetir loop can only end with Hasta Que condition (until).
Para counting downDiffers from default: To count down you must write Con Paso -1; without it, Para i <- 3 Hasta 1 doesn't run at all.
Segun with whole numbersDiffers from default: The value a Segun checks, and its options, must be whole numbers.

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.
