I have to write a program that counts the number of vowels and output the percentage of usage based on the number of vowels and of letters in general then i need to give the percentage of consonants used.

oh, thats easy.
if its only one word, then:
use the length function, like length(word), that will count the number of letters in the word.
then use the index function with a for loop and a counter
like

for a: 1..length(word)
if index ("aeiouAEIOU", word) not = 0 then
counter:=counter+1
end if
end for

the counter counts the number of vowels,
then
use the number of vowels divide by number of letters, for percentage,
like
percentageofvowels:=counter/length(word)
the constanants is the number of letters minus vowels:
constanants:=length(word)-counter
percentageofcon:=constanants/length(word)

umm it's not for one word. I have to open a text file and then count the number of vowels and upper and lower cases must be counted. After i need to output all the percentages.

um.. txt files are not my area of expertise, but if its not one word then make a loop that adds all the strings into one variable, then count the number of spaces in that variable but using a counter:
for a: 1..length(text)
if index (" ", text(a)) not = 0 then
spacecounter+=1
end for
you can count the upper cases and lower caseswith a if statement and the ord function.
then do the percentages, if you have trouble reading the text file, Im sure there's plenty of tutorial material around here addressing that.

This is what i have so far for the program:
var word : string
var text : int
const vowel := "aeiouAEIOU"
var count : int := 0
open : text, "NewText.txt", get

loop
delay (1000)
exit when eof (text)
get : text, word
put word, " " ..
for a : 1 .. length (word)
exit when eof (text)
if index (vowel, word (a)) not= 0 then
count := count + 1
end if
end for
put "The number of occurances : ", count, "."
end loop
The problem is it reads each word and outputs the number of vowels. I want it to read the whole text then output the number of vowels. What do i change???

I think you have to keep getting everything and adding all the string into one string variable, THEN after that you start counting, I've never actually worked with txt files b4, but Im guessing keep adding to the string until eof.
like you start out with:
var text: string:=""
then after you get one line and put it into a variable, lets call that line: line,
then you go
string:=string+line, and keep on adding untill the file is finished. the you look for it in the whole string, maybe
