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.
