[DDI-users] DDI software that recognizes extended Stata/SAS missing values?

[Bob McConnaughey]

Dear Folks:
    Do any of the DDI documentation/codebook generating packages handle
extended Stata/SAS missing values? .a-.z ; "."?  Our analysis datasets (as
opposed to the original questionnaires) invariably use multiple sets of
special missing codes, and converting every thing into faux numeric
missings (-1---9) for instance kind of defeats the purpose.
any way forwards will be most appreciated.
thanks
bob
