Hello David,

Great !  I'm glad it works for you :)

Ok no problem then. But if your buffer has a constant size, then wy not
put it on the stack like this:
  Buffer: array[0..TempSize] of char;
  // receive in buffer

Yes that's another option. Then you only have 1 time allocation, but see
paragraph above.

Difficult to say wahts best because it is depending on what you exacly
wants or have to do with it.

- if you have to save it to a file then you can:
  - open the file at first packet
  - receive in buffer
  - write buffer direkt to file
  - close file at last packet
  -- the most fast is to use the low level routines: FileOpen(), etc...

- TFileStream is another option, somewhat slower

- if you have to do other things with it then you can
  - use a TMemoryStream
  - or a dynamicly allocate buffer that you take care yurself

  Both of course will reallocate when data grow, however you can for
  both options set the size at first, then also only 1 memallcoation and
  no reallocation.

- array of pointer seems more difficult. Dont think you will have
  advantage using it.
