a record is a basically a user defined type, this means we are no longer restricted to things like ints and strings

i know wat im saying is basically wat the tutorial above said, but can u post wat u dont get about it?

And hence you read that Tut, which, I might add, is one of the best tuts around.  It'll have you compacting your code in no time.

Also, you can write a record as a whole to a file, instead of every single variable, and save many lines...

so for example instead of

var x, y, z : int
x := 9
y := 10
z := 15
var a, b, c : string
a := "a"
b := "b"
c := "c"
var fileNo : int
open : fileNo, "filename.txt", write
write : fileNo, x
write : fileNo, y
write : fileNo, z
write : fileNo, a
write : fileNo, b
write : fileNo, c
close : fileNo

you can have

type ter :
    record
        x : int
        y : int
        z : int
        a : string
        b : string
        c : string
    end record
var let : ter
let.x := 9
let.y := 10
let.z := 15
let.a := "a"
let.b := "b"
let.c := "c"
var fileNo : int
open : fileNo, "filename.txt, write
write : fileNo, let
close : fileNo

now, even though there are 3 more lines with a record, you don't have to risk forgetting to write one of the variables since all of them are included in writeing a record
