-  will raise an exception.

-  is 75%

-  backwards.  The special case of setting the stream position to zero is
-  allowed.  Seeking forward decompresses data until the requested position in
-  the uncompressed data has been reached.  Seeking backwards, seeking relative
-  to the end of the stream, requesting the size of the stream, and writing to
-  the stream will raise an exception.
-
-  The Position property returns the number of bytes of uncompressed data that
-  have been read from the stream so far.
-
-  The OnProgress event is called each time the internal input buffer of
-  compressed data is exhausted and the next block is read from the input stream.

-//   Important note about DLL memory management in a VCL DLL:
-//
-//
-//
-// If your DLL uses VCL and exports any functions that pass VCL String objects
-// (or structs/classes containing nested Strings) as parameter or function
-// results, you will need to build both your DLL project and any EXE projects
-// that use your DLL with the dynamic RTL (the RTL DLL).  This will change your
-// DLL and its calling EXE's to use BORLNDMM.DLL as their memory manager. In
-// these cases, the file BORLNDMM.DLL should be deployed along with your DLL
-// and the RTL DLL (CP3240MT.DLL). To avoid the requiring BORLNDMM.DLL in
-// these situations, pass string information using "char *" or ShortString
-// parameters and then link with the static RTL.
