The values specified for the SPDE engine LIBNAME statement primary
path, as well as for the DATAPATH=, INDEXPATH=, and METAPATH= options,
are stored internally in the data set when it is created.  If any part
of any of the paths is changed, the engine cannot process the data set
and messages like:

  WARNING: One or more indexes are corrupted on data set.
  ERROR: Data set needs REPAIR operation to fixup incomplete
         information.

or:

  ERROR: File libref.member.DATA does not exist.

may be produced.  After an SPDE data set is created, ensure the
identical paths that were used when the data was created are used for
each subsequent access.

Beginning in SAS 9.2, the LISTFILES=YES data set option is available
for use with PROC CONTENTS to list the complete pathnames of all the
component files that comprise the data set.
