Thanks ,that worked, I don't know how I let that slip. Brad Hall <[EMAIL PROTECTED]> wrote: The 3rd parameter of the Copy function is the "number" of characters to copy from the string, not the position in the string to copy "to".
eg: Copy(Data, 6, 8) will start copying from position 6 in the string Data, for a total of 8 characters (or EOL) Copy(Data, 11, 13) will start copying from position 11 in the string Data, for a total of 13 characters (or EOL) For the results you require, you will need Copy(Data, 1, 3); Copy(Data, 6, 3); Copy(Data, 11, 3); ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Curtis cloud Sent: Friday, 5 January 2007 13:23 To: [email protected] Subject: Re: [delphi-en] Using the copy function to separate data Joe, I was looking for the following results: 0.0 0.1 0.0 r/Curtis.. joe wilcox <[EMAIL PROTECTED] <mailto:falon5000%40yahoo.com> > wrote: Using your sample code, I wrote this simple test: procedure TfrmMain.Button1Click(Sender: TObject); var Data : string; begin Data := '0.0000.1370. 000'; memo.lines.add( Copy (Data, 1, 3)); memo.lines.add( Copy (Data, 6, 8)); memo.lines.add( Copy (Data, 11, 13)); end; Here's the result I got - 0.0 0.1370. 0. 000 That's pretty much what you're looking for, isn't it?

The data that I receive has spaces and tabs in the middle of the string. Once I receive the data I remove all spaces and tabs to get a single stream of data. After I receive the stream I attempt to parse the data into segments using the copy function. My problem is this when I look at the stream the data looks fine but when I use the copy funtion it does not work properly on the data. Here is an example : Single stream from a telnet connection 0.0000.1370. 000 Data := ' 0.0000.1370. 000' Copy (Data, 1, 3) yield value 0.0 which is fine. Copy (Data, 6, 8) yields value 0.0000.0 which is wrong. Copy (Data, 11, 13) yields value 0.0000.0000. 0 which is wrong. I'm not sure why I am not receiving the correct data. r/Curtis.. ____________ _________ _________ _________ _________ __ Do You Yahoo!? Tired of spam? Yahoo!
