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);

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?

Subject: [delphi-en] Using the copy function to separate data
ALL,
I have a telnet connection to a server computer that constant broadcast
data to me each second. 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..
