The OSIRIS engine is a read-only engine that enables you to access OSIRIS
data and dictionary files as if they were SAS data files.
To assign a libref to an OSIRIS file so that you can access it, use this form
of the LIBNAME statement:
|
LIBNAME libref OSIRIS data-filename
DICT='dictionary-filename';
|
This form of the LIBNAME statement takes the following
arguments:
-
libref
-
is a SAS libref.
-
OSIRIS
-
specifies the OSIRIS engine.
-
data-filename
-
specifies the physical filename of the data
file.
-
dictionary-filename
-
specifies the physical filename of the data
dictionary.
If the libref also appears as a fileref, the data-filename can be omitted in the LIBNAME statement. (See the
next
example.) However, you must still use the DICT= option because the engine
requires both files.
You do not need to use a LIBNAME statement before running
PROC CONVERT on an OSIRIS file.
OSIRIS data files do not have individual
names. Therefore,
you can use a member name of your choice in SAS programs for OSIRIS files.
You can also use the member name _FIRST_ for an OSIRIS file.
You can also use the same dictionary file with different
OSIRIS data files. In this case, code a separate LIBNAME statement for each
data file.
The contents of the dictionary file determine the file
layout of the data file under OSIRIS. A data file has no other specific layout.
The layout of an OSIRIS data dictionary is consistent
across operating environments. Although the OSIRIS software runs only under
OS/390 and CMS, the OSIRIS engine in the SAS System accepts a CMS data dictionary
in any other operating environment running the SAS System. The data dictionary
and data files should not be converted between EBCDIC and ASCII, however,
because the OSIRIS engine expects EBCDIC data.
Suppose you want to read the data file TEMP OSIRDATA
and the data dictionary is TEMP OSIRDICT. The following statements assign
a libref to read the data in order, then run the CONTENTS and PRINT procedures
on the file:
libname xxx osiris 'temp osirdata' dict='temp osirdict';
proc contents data=xxx._first_;
proc print data=xxx._first_;
