Hello, Every one

  Could anybody tell me that how to assign all values to a record
typed variable? I mean that in C I can assign a struct variable
such as:
  struct aaa {
    x,y:int;
  };
  struct aaa a;
  a={1,0}; //Assign in single statement
  How to implement it? The following code seems not working:
  a:=(1,0);
  Help me!
  Thank you very much.

... and in Pascal you cannot. You can only initialize records when they are declared.

Hello.

Could anybody tell me that how to assign all values to a record typed variable? I mean that in C I can assign a struct variable such as:

type
   aaa = record
     x, y : Integer
   end;
var
   a : aaa;
begin
   with a do begin
      x := 1; y := 0
   end;
end.

Neat, simple, elegent. Unlike C.

I fI remember correctly, this worked in TP, at least:

a={x:1;y:0};

Only for typed constant declarations.

I'm quite sure that won't work, since { ... } is a comment :)

Of course it won't. Silly me. :/
It should be ordinary parenthesises.

I remember now exactly how I did it in TP. I simply made a typed constant, then any variable of the same record type can be assigned the value of the constant.

The only real difference from the C implementation is that you have to give the value a name. I bet the final compiled code will look very similar...
