{hi:kldb92_3d_to_bibb()} {hline 2} Translate 3-digit KldB-1992 to BIBB occupational fields (2 digit)

{title:Syntax}

        {cmd:kldb92_3d_to_bibb(}{varname} [{help crosswalk##case:{it:case}}]{cmd:)}

{pstd}
    where {it:varname} contains 3-digit KldB-1992 codes.

{title:Description}

{pstd}
    {helpb kldbrecode} table translating KldB-1992 occupational orders (3 digit codes) to BIBB occupational fields (2 digit)
    codes using {helpb crosswalk}.

{pstd}
    Besides the original crosswalk from the BIBB, this {helpb kldbrecode} table provides a modified version by Hans Gerhardt.
    The modified version improves the overlap in microcensus 2012 data when recoding both KldB-1992 and KldB-2010 codes to BIBB occupational fields. 
    Therefore, it provides more consistent time series with microcensus data.
    To access the modified crosswalk from the second column specify the {help crosswalk##case:{it:case argument}}.
