lolz, i did this for extra credit this september, although i didnt know that there was a function for it Crying or Very sad . What i did is that i used the number 256 (1 as the 9th digit of binary) and kept deviding it by 2, then checking to see if i could minus certain numbers from it. heres the post for it, and there are tons of other submissions for it too. study it.

Use "length (variable)"

Ex:
code:
var a :string
put "Write something"
get a:*
put "The length of your writing masterpiece is ",length (a)," characters."

length(variable) is for strings. So in order to use that you would have to convert the interger into a string using intstr()

ok thanks, i also need to be able to extract a certain char from the string, and i remember doing that yet cant remember for the life of me what the function was
i remember it including * s to signify the last char in the string

i don't know about the *s but you just go something like this
code:
Character:=String(number)

Character is the character you want to isolate. String is the string and number is the number of the character. for example this would print "r" becuase "r" is the third character in the string "turing"
code:
var text:string:="turing"
put text(3)

Treat strings like you would arrays of characters.

var x : string := "abcdefghijklmn"
put x (3)
-> puts out "c"

put x (5..*-2)
- >puts out "efghijkl"

You can use index and length for more in-depth string manipulation.
