VisualG - Exercise with procedure

Navigation
0

Good afternoon guys, all right?

I have an Algorithm I exercise, and I'm stuck in a doubt. The question:

- Write a procedure that receives an integer and prints it in the extended form. For example, for 1 the desired output is "One." The function must be able to generate the length of numbers from 1 to 15 inclusive. If an unsupported number is received the procedure should display an error message. Also create an algorithm that reads an integer value and call the procedure created above for printing the extended number.

My code: 

algoritmo "APS09"
var
   num: inteiro

procedimento FormaExtensa(n:inteiro)
var
   extenso:caracter
inicio
      escolha n
              caso "1"
                   extenso <- "Um"
              caso "2"
                   extenso <- "Dois"
              caso "3"
                   extenso <- "Três"
              caso "4"
                   extenso <- "Quatro"
              caso "5"
                   extenso <- "Cinco"
              caso "6"
                   extenso <- "Seis"
              caso "7"
                   extenso <- "Sete"
              caso "8"
                   extenso <- "Oito"
              caso "9"
                   extenso <- "Nove"
              caso "10"
                   extenso <- "Dez"
              caso "11"
                   extenso <- "Onze"
              caso "12"
                   extenso <- "Doze"
              caso "13"
                   extenso <- "Treze"
              caso "14"
                   extenso <- "Quatorze"
              caso "15"
                   extenso <- "Quinze"
              outrocaso
                   extenso <- "Número não compatível"
      fimescolha
      escreval(extenso)
fimprocedimento

inicio

      escreva("Digite um número até 15: ")
      leia(num)

      FormaExtensa(num)

fimalgoritmo

However, at the time of running, it asks to type the correct number, however, any number that I type, it gives an error in caso "1" and says that I expected an INTEGER. I still do not understand where he expected an integer value.

Can anyone help me with this? Thank you in advance.

[RESOLUTION]

I just removed the quotation marks from the case, as suggested in response to the post. 

caso 1
                   extenso <- "Um"
              caso 2
                   extenso <- "Dois"
              caso 3
                   extenso <- "Três"
              caso 4
                   extenso <- "Quatro"
              caso 5
                   extenso <- "Cinco"
              caso 6
                   extenso <- "Seis"
              caso 7
                   extenso <- "Sete"
              caso 8
                   extenso <- "Oito"
              caso 9
                   extenso <- "Nove"
              caso 10
                   extenso <- "Dez"
              caso 11
                   extenso <- "Onze"
              caso 12
                   extenso <- "Doze"
              caso 13
                   extenso <- "Treze"
              caso 14
                   extenso <- "Quatorze"
              caso 15
                   extenso <- "Quinze"

Dude, it's not because you put two double quotation marks, but he expects to receive a number, but this is compared to a string, in case it would look like this: 

escolha n:
    case 1 extenso <- "UM"
    case 2 extenso <- "DOIS"
    ...
