-
- Beware when using VMS_SHARE to encode binary data. SERIOUS amounts of
- CPU time are consumed BOTH in the encoding and decoding.
-
- I did the original work on adding the file attribute preservation support
- to VMS_SHARE and my goals at that time were to follow along with the basic
- premise of a "shar" file - that it be self sufficient, i.e it does not
- require any "extra" software be resident on the machine that is doing the
- unpacking. The original problem was to be able to pass executable files.
-
- If BOTH you and the receiving end of the transfer have access to MFTU to
- encode the file then prepacking with MFTU is certainly a preferable
- method. You will also then be able to move any arbitrary binary file
- instead of the limited set that VMS_SHARE will handle. VMS_SHARE is
- basically limited by the underlying TPU implementation and hence will only
- deal with sequential files that have reasonable record length. MFTU will
- encode any file and preserve all of its file structure attributes.
