Subject: ANSI X3.64

This is probably going to contain far more than you wanted to know,
but...

Any ANSI standard can be ordered through ANSI's order department, 1430
Broadway, New York, NY 10018.  I would suggest that you try to get them
on the telephone and get current ordering and price information.  They
tend to want payment in advance, except for ANSI members.  ANSI
standards that have been approved as Federal Info Processing Standards
(FIPS) are often available to government activities through NBS, I
think, and that route might be faster and cheaper.

If I recall, X3.64 is now under revision, partially to move it closer to
an international standard that used it as a starting point and got
ahead.  So you might try to get the name of the corresponding ISO
standard from the order department and order it as well.  The official
name of X3.64, which you may need, is "Additional Controls for Use with
American National Standard Code for Information Interchange".

ANSI standards are not, in general, available in machine readable form.
While most of the technical committees developing the things typically
have them that way, we have been trying intermittently for some years to
get a policy statement from ANSI on the release of machine-readable
copies; none has been forthcoming.

X3.64 is the responsibility of technical committee X3L2, Codes and
Character Sets.  As a last resort, the chair of that committee is Thomas
Hastings of DEC, 617/493-8109 - he would have current status information
on whatever is going on.
