Another Record Error

[Justin_]

code:

var website : flexible array 1 .. 1 of         record     %struct equivelant             url_list    : array 1 .. 20 of string             %turing doesn't support flexible arrays within records.             search_found  : int             url_count     : int :=0     %To determine how many links there are.          %   url         : string             file_stream   : int             netStream     : int             urlNum        : int := 0         end record

I'm getting an error, it highlights ":=o" for both urlNum and url_count. Does this mean I'm initializing my record variables incorrectly?

The elements in a record cannot be initialized directly. They are basically descriptions of what the variable will contain. You wouldn't want to initialize them right away anyway - that wouldn't be fun.

You should, however, create a function to initialize them:

code:

type myType :    record       name : string       number : int       face : string    end record function init_MT (inName : string, inNum : int, inFace : string) : myType    var temp : myType    temp.name := inName    temp.number := inNum    temp.face := inFace    result temp end init_MT % Alternatively, if you do want certain fields to automatically be initialized to a certain value: function init_MT_def (inName : string) : myType    var temp : myType    temp.name := inName    temp.number := 5    temp.face := "Sad"    result temp end init_MT_def

If you know how to use them, a class is a better solution than using a record.

Yeah well, my record just so happens to be used in a flexible array, so I really can't see it being too efficient having to initilaize every element inside the array IF it gets created.

I wish i knew about classes if they could help.

Read Cervantes Tut on it. It's a long haul, but it will introduce you and guide you through a fair deal.

The other way of doing it is:

code:

var my_coord2d :     record         x, y : int     end record     := init (5, 7)

I'm fairly certain the above works, though I doubt if it would work on types:

code:

type coord2d :     record         x, y : int     end record     := init (5, 7) var my_coord2d : coord2d

I highly doubt that would work, but it's worth a try. This calls for a new acronym: NOWNOW Not on Windows now

But yes: objects.
