(OT) Delphi / Pascal

[sunburnt]

Could someone tell me why this doesn't work? I have yet to find a decent Pascal / Delphi Forum....

function MakePacket(ID: string; Data: string):string;
var s1:string; i1:integer;
begin

i1 := length(Data) + 4; // length of packet
s1 := StringOfChar(' ',2); //initialize string * 2

CopyMemory(@s1,@i1,2); //convert length to string
MakePacket := (ID) + s1 + Data; //make packet.

end;

What is the output and are you using /0 terminated strings or Pascal style?

Why add 4 to the length (byte?)

Cheers,

P.

The error occurs at the CopyMemory -- at this point the program will lock up until it runs out of memory. The output should look like this: ID (two bytes) + Legth (two bytes) + Data (x bytes)
This is why I add 4 to the Length.
