Summary
Procedures
PROC DATASETS <LIBRARY=libref <MEMTYPE=mtype(s)>>;
The MEMTYPE= option restricts processing to a certain type or types of SAS files
and restricts the library directory listing to SAS files of the specified member types.
DATASETS Procedure Statements
CONTENTS <DATA=<libref>.SAS-data-set> <NODS> <SHORT> <VARNUM> ;
describes the contents of a specific SAS data set in the library. The default data set is
the most recently created data set for the job or session. For the CONTENTS
statement in PROC DATASETS, when you specify DATA=, the default libref is the
procedure input library. However, for the CONTENTS procedure, the default libref
is either WORK or USER.
Use the NODS option with the keyword _ALL_ in the DATA= option to produce
only the directory listing of the library in SAS output. That is, the NODS option
suppresses the contents of individual files. You cannot use the NODS option when
you specify only one SAS data set in the DATA= option.
The SHORT option produces only an alphabetical list of variable names, index
information, integrity constraint information, and sort information for the SAS data
set.
The VARNUM option produces a list of variable names in the order in which they
were defined, which is their logical position in the data set. By default, the
CONTENTS statement lists variables alphabetically.
