Dear Mr Hjalmarson,
Did you send a message answering to Christian Galinsky and giving the asked specifications ?
In my opinion:
1-There is no good possible solution within an alpha-2 coding scheme like ISO 639-1;
2-But there seems to be a possible solution if you pass to an alpha-3 coding scheme like ISO 639-2, in this case:
a/ "und" is the code element representing "undetermined language (name)"; 
b/ "mul" is the code element representing "multiple languages (names)" ;
c: the list qaa-qtz of code elements reserved for local use could very well be used to represent the list of "machine languages you are wanting to code ( Languages designed exclusively for machine use, such as computer programming languages, are explicitely excluded of the official ISO 639-2 coding scheme  by clause 1-Scope of the standard, so that there could be no intersection between the machine language (names) coded by you inside the list "qaa-qtz" and the official ISO 639-2 "language names" code elements.
Bien cordialement.

Mr. Hjalmarson: It would also be helpful if you could provide a little info about your application scenario. In particular, if you need metadata elements used in public interchange protocols, then that might be significant: some protocols may already specify use of alpha-3 identifiers from ISO 639-2 or ISO 639-3, or may specify derivative conventions such as IETF BCP 47 that reference these other parts of ISO 639.

Dear Mr. Hjalmarson,
 
I have forwarded your request to colleagues of ISO/TC 37, but I think that it should be properly dealt with by the Joint Advisory Committee of ISO 639 „Codes for the representation of names of languages“.
 
Could you please specify what you mean under
- “machine language”? (I assume not programming language)
- “multi-language”: in what sense? (several languages in one text, same representation for a semantic unit in several languages?)
- “undefined language”?
 
In any case there seem to be more needs for language symbols around than we could so far foresee…
 
Any “individualistic” solution without international coordination will sooner or later lead to incompatibility/interoperability problems.
 
Best regards
Christian

Hi,
 
Thanks for the information.
 
Is there any information that you can provide in guidance on what to use if we want to identify
- manchine language
- multi-language
- undefined language
 
What would be the recommendation for to identify the above "languages"?
If we are to assign "own codes" for to identify the above "languages" what are we to consider?
- what characters are not to be used
- how many characters 
 
Best regards,
Mikael Hjalmarson
