Reading a mainframe PDS (SAS Library) using a sas program

THALLA_REDDY — Mon, 08 Feb 2021 13:41:03 GMT

Hi all,

I have to read a Mainframe PDS which is having SAS Program members in it by passing the PDS using a JCL. I have to read one by one and have to get the creation date and user_id as highlighted in below snap.

Please help me with the SAS Code logic for the same.

thanks in advance

I no longer have access to a mainframe to test my code, but something like this should work:

data _null_;
   /* Assign a fileref to the PDS */
   _rc=filename("myPDS","mydata.my.pdsfile");
   _did=dopen("myPDS");
   if _did ne 0 then do;
      putlog "ERROR: Unable to open PDS to look at members";
      _rc=filename("myPDS");
      stop;
   end;
   do _i=1 to dnum(did);
      /* Get info for each PDS member */
      MemberName=dread(did,i);
      _rc=filename("thisMem",cats("myPDS(",MemberName,")","S");
      _fid=fopen("thisMem");
      do _j=1 to foptnum(_fid);
         infoname=foptname(_fid,_j);
         infovalue=finfo(_fid,infoname);
         output;
      end;
      _rc=fclose(_fid);
      _rc=filename("thisMem");
   end;
   _rc=dclose(_did);
   _rc=filename("myPDS");
run;

Hope this at least gets you started 🙂

Hi,

I am getting return code 1 instead of zero with this code. Can anyone help me to move forward on this?

thanks,

Hi This is the code that I have created

OPTIONS MISSING = ' ' SYMBOLGEN;

%LET PDSNAME = %ADDTICKS(testpds.jcllib);

DATA PDSCHK;
_RC = FILENAME("MYPDS",&PDSNAME);
_DID = DOPEN("MYPDS");
IF _DID NE 0 THEN DO;
PUTLOG "ERROR: UNABLE TO OPEN PDS TO LOOK MEMBERS IN IT";
_RC = FILENAME("MYPDS");
/* STOP; */
END;
ELSE DO;
PUTLOG "PDS opened successfully";
END;
DO _I = 1 TO DNUM(_DID);
MEMBERNAME = DREAD(_DID,I);
_RC = FILENAME("THISMEM",CATS("MYPDS(",MEMBERNAME,")","S"));
_FID = FOPEN("THISMEM");

DO _J = 1 TO FOPTNUM(_FID);
INFONAME = FOPTNAME(_FID,_J);
INFOVALUE = FINFO(_FID,INFONAME);
OUTPUT;
END;
_RC = FCLOSE(_FID);
_RC = FILENAME("THISMEM");
END;
_RC = DCLOSE(_DID);
_RC = FILENAME("MYPDS");
RUN;

The log is
