Here is the list. Remember that 1 stands for CH, 2 for LL, 3 for RR. People will enter CARRO and your program will look for CA3O to se if it is good.

Dear Graham,
 
As you know, when a person enters ch, ll or rr, the program must convert that to 1, 2 or 3 so that it matches the list.
 
There are other conversions to be made, regarding diacritical marks:
 
á --> a
é --> e
è--> e
í -->  i
î--> i
ó--> o
ú--> u
ü--> u

That is to say, if a player enters 'á' the program converts it to 'a', just like it converts 'ch' to 1 so that it matches the list.
 
For ch,ll, and rr, there is another possibility: converting the lexicon symbols 1, 2 and 3 to ch,ll, and rr.

Let me tell you how I would like the program to display things.
 
First of all, the title of the program, which is:
 
"Juez Virtual FISE 1.0". 
 
That should be displayed at the top of the page and with letters biggers than the rest.
 
Then, above the window where words will be typed to see if they are valid or not, the following message:
 
"Teclee la palabra cuya validez desea consultar".
 
And below the window, once the word is entered, the following message, depending on whether the word is valid or not.
 
If the word is valid:
 
"PALABRA ACEPTADA" (with green letters)
 
If the word is not valid:
 
"PALABRA NO ACEPTADA" (with red letters).
 
Now let me recap the list of conversions the program has to make in order to have the word typed fit the lexicon.
 
* Every capital letter turned into a non capital letter.
* Every pair ch,ll or rr turned into 1,2,3 respectively.
* á é í ó ú turned into a e i o u
* ü turned into u
* è turned into e
* î turned into i
* Á É Í Ó Ú turned into a e i o u
* Ü turned into u
* È turned into e
* Î turned into i

Also remember there is a special letter in the Spanish alphabet: ñ
 
The non-capital form is 'ñ' and that is how it appears in the lexicon.
 
The capital form is Ñ and it should be turned into ñ.

If the word entered doesn't have a number of tiles greater or equal than two, and lower or equal to fifteen, this is the error message to display:
 
"La palabra consultada debe tener entre dos y quince fichas".
 
Note that digraphs CH, LL, and RR are two characters but one tile. Here what matters is tiles.
 
If the word entered has k, w, or any other character, for example numbers or signs, this is the error message to display:
 
"La palabra consultada debe estar formada por letras de la A a la Z excepto K y W".
