PSeInt profile ITSAV CLC

These are the rules of the ITSAV CLC profile, explained simply, with an example that follows them and opens in Codoritmo with one click.

How its author describes it

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

Perfil para Ingenieria en Sistemas Computacionales en el Instituto Tecnológico Superior de Alvarado (enviado por el ISC. Crispín León Cruz, LiveCode).

In short

What changes compared with Codoritmo's default profile:

Every variable must be declared with Definir
The Para counter is protected
You can assign with = as well as <-
Arrays start at 0
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 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 use: Not checked. It's still good practice to give every variable a value before using it.
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 names: Allowed: a variable can be called año or posición.

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 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 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.
