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?

[Clayton]

i basically dont understand how i can use them and how to use them

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

code:

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

code:

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

ok thnx i think im starting to understand now
