PSeInt profile UIDE

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

In short

What changes compared with Codoritmo's default profile:

Every variable must be declared with Definir
The Para counter is protected
No accents or ñ in variable names
Entonces, Hacer and endings such as FinSi must be written in full
No Para Cada (for each) loop

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 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 syntaxDiffers from default: Strict: write every structure in full, with Entonces, Hacer and one-word endings such as FinSi and FinMientras.
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 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 index: Arrays start at 1: after Dimension notas[3] the slots are notas[1], notas[2] and notas[3].
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 loopDiffers from default: Not available: go through arrays with a Para and an index.
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.
