How its author describes it

The profile's original text, in Spanish, as distributed with PSeInt.

Perfil para la asignatura Ciencias de la Computación. de 3ero NS. en el Colegio Intelecto (enviado por la profesora Lisibonny Beato).

In short

What changes compared with Codoritmo's default profile:

Every variable must be declared with Definir
Every variable needs a value before it is used
The Para counter is protected
No accents or ñ in variable names
You can assign with = as well as <-
Only the symbols & | ~ % work as operators
No conditions like Es Par: comparisons use operators
Arrays start at 0
Array sizes must be fixed numbers
Counting down needs Con Paso -1
Segun only works with whole numbers
No SubProceso or Funcion of your own

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 DefinirDiffers from default: Required. Before using a variable you must declare it with its type, for example Definir edad Como Entero. That includes the counter of every Para.
Give a value before useDiffers from default: Required. Reading a variable, or an array slot, that has no value yet stops the program with an error. That's why accumulators start with something like suma <- 0.
Protected Para counterDiffers from default: Inside a Para you can't change the counter, and once the loop ends the counter has no value, so don't use it afterwards.
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 =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 operatorsDiffers from default: Symbols only: & instead of Y (and), | instead of O (or), ~ instead of NO (not) and % instead of MOD.
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 variableDiffers from default: Not allowed: the size in Dimension must be a fixed number, such as Dimension datos[10].
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 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 functionsDiffers from default: Not allowed: the whole program goes inside Algoritmo … FinAlgoritmo.
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.
