atip_1553 package - questions

[Gary Funck]

A while back, I fetched the 1553 package at ajpo.sei.cmu in the file:

    atip1553.tar.Z

and have just gotten around to trying to use the code.  There are a couple
of questions that I have so far, and I'm wondering if someone
may have already found the answers:

1) The files are numbered f00.ada through f74.ada, except f13.ada is
left out.  Is this inteneded, along the lines of leaving out the
13th story in a building?

2) There are references to a package called CONDITION_HANDLING, but
the package is not present in the source directory:

f04.ada:with CONDITION_HANDLING;
f04.ada:    STATUS       :  CONDITION_HANDLING.COND_VALUE_TYPE; 
f05.ada:with CONDITION_HANDLING;
f05.ada:    Status      : CONDITION_HANDLING.COND_VALUE_TYPE;                  
               --| Return code from system call
f05.ada:    if not CONDITION_HANDLING.Success(Status) then
f05.ada:          if not CONDITION_HANDLING.Success(Status) then
f05.ada:          if not CONDITION_HANDLING.Success(Status) then
f05.ada:            if not CONDITION_HANDLING.Success(IO_Stat.Status) then
f05.ada:              if not CONDITION_HANDLING.Success(Status) then
f20.ada:with CONDITION_HANDLING;
f20.ada:  package CHND renames CONDITION_HANDLING;
f30.ada:with CONDITION_HANDLING; use CONDITION_HANDLING;
f30.ada:    Status   : CONDITION_HANDLING.COND_VALUE_TYPE;

It seems that COND_VALUE_TYPE can be defined as an integer, but I'm
just wondering what the intent is behind leaving CONDITION_HANDLING
out of the source release?  There is no memntion of this in the read_me file.

3) Does anyone have an e-mail address on the author(s) of this package?
(saveral of the headers mention Bob Johnson, department : NATC,
Manned Flight Simulator, SETD, CTSD, SY32)

thanks for any pointers/help,

- Gary

This type and function call are references to one of the packages supplied
by DEC with their VAX Ada (which by the way is an excellent product for a
good but not great machine).

I am reading a document that uses the EXPRESS Language to represent data
structures. Does anyone have a on-line summary of EXPRESS that they can
forward to me? Has anyone done any mapping of EXPRESS data types to Ada data
types?

Well, that strongly implies that the 1553 code isn't portable outside
of a VAX/VMS environment...
