I dont know why your so rude, im just having trouble splitting the word into letters. I can get the program to get different words but then i need to be able to split up the word into its letters.

var file_contents : flexible array 1 .. 0 of string
var stream : int
open : stream, "words.txt", get
loop
exit when eof (stream)
new file_contents, upper (file_contents) + 1
get : stream, file_contents (upper (file_contents))
end loop
loop
put file_contents (stream)
stream := stream +1
delay (1000)
end loop

now that gets me the different words but i need to split each word into its letters

code:

var letter: array 1..length (word)

for x 1..length (word)
     letter (x) := word (x)
end for


This will assign every element of 'letter' one of the letters of 'word'. To call up a random letter, use a random number and insert that into letter (?).

If you haven't done string manipulation yet, I suggest you look into it.

I had a test on string manipulation yeasterday!

var letter: array 1..length (file_contents (stream))

for x: 1..length (file_contents (stream))
letter (x):= (file_contents(stream))
end for



is my code now using what you told me. Now the only problem is the for, when ever i click run it says syntax error at 'for' expected 'of'... any ideas?

If you know this little about arrays, why are you using them?

it should read:

code:

var letter: array 1..lenght (file_contents (stream)) of string
