Subject: [DDI-users] SAS CNTLIN CNTLOUT dataset in DDI31
SAS (and Stata) are a little different from SPSS in that labels for
values are defined independently from variables. A Variable then
contains a pointer to a set of labels (formats).
SAS has the capability to create a dataset containing a collection of
label definitions, a "CNTLOUT" dataset. This can be then used as a
"CNTLIN" dataset to recreate the collection of labels. Preserving a SAS
dataset involves preserving the dataset itself and the associated CNTLIN
dataset.
Since the structure of the CNTLIN dataset is always the same, it is a
good candidate for a DDI 3.1 resource package. A draft of such a package
can be found at:

UT_ResourcePackage.xml
A SAS program which writes the above DDI file can be found at:

Feedback would be appreciated.
