SAS Mainframe : Create Permanent Dataset

kumarsandip975 — Fri, 06 Jan 2023 14:30:54 GMT

Dear Members,

Can you please help how to create mainframe dataset through data step on SAS STUDIO.

Note: I have already remote signon macro where I can login mainframe platform and code data step inside rsubmit/endrsubmit.

Code sample:

%remote_signon();

Rsubmit;
LIBNAME LIB1 "MAINFRAME.PDS" ;
Data LIB1.TEST1;
Var1="ABCD";
run;
Endrsubmit ;

Did that work? If not then what error messages did you get?

It's been many years since I last used SAS on a mainframe, but I don't think you use PDSs (Partitioned Datsets) to store SAS datasets. From recollection you use normal sequential files. Here's the type of LIBNAME I'd expect to see:

libname newlib 'abc.my.saslib' disp=(new,catlg);

Libraries on a mainframe have to be partitioned sets, otherwise you would not have a means to find individual datasets quickly, or update them without having to rewrite the whole library.

PS it seems that mainframe SAS today mainly uses the UNIX-style filesystem, where a library is a directory. Which would imply that one has to use a UNIX absolute path for the LIBNAME to work.

@Kurt_Bremser - After some research I found this very helpful reference regarding mainframe SAS libraries: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/hosto390/p0zcnanujjomx7n16r8vajm70x0s.htm

It appears z/OS SAS library files are analogous to z/OS PDSs but are not the same. z/OS PDSs use a DSORG of PO while SAS library files use DSORG of PS.
