I have some questions/comments on 7.7.2,7.7.3 for datatype
encode/decode (comments based on 25 Oct 96 draft):

- 151/30: I assume the example #'s given are a reference to the
MPI-1.1 standard? We need the correct reference.

- 151/30: I find the examples hard to follow. Are they up to date
relative to the tables? For example, where did the "U" come from.
Also, I think it might be useful (for at least one example) to outline
exactly what would go in each byte since this is a byte encoding.

- 153/25: What happened to the optional datatypes? I know you sent me
some mail about resolving it, Richard, but now I don't understand what
happened.

Minor corrections:

- 149/28: "If comm may be one" wording off

- 150/1: "MPI_TYPE_ENCODE communicator comm" -> "MPI_TYPE_ENCODE with
communicator comm"

- 151+: References to tables non-std (Ricard: I will try to fix this
once I get a new version from you)

- 151/23: "toplevel" -> "top level"

- 153/9-24: It would be nice to have all the numbers in a straight
column.
