MYRA,

IF YOU TAKE THE REFERENCE TO THE SAS LIBRARY OUT OF THE JCL YOU CAN USE THE SAS LIBNAME AND LIBNAME CLEAR STATEMENTS TO ACCOMPLISH WHAT YOU WANT.

HERE IS A SMALL JOB THAT CREATES A DATA SET FROM A READ-ONLY LOCATION, THEN IT CLEARS OUT THE LIBNAME ESTABLISHES THE SAME LIBNAME AGAIN WITH DISP=OLD WRITES A DATA SET TO THE LIBRARY THEN DELETES THE DATA SET JUST WRITTEN FROM THE LIBREF.

// YOUR JCL ... //WORK DD SPACE=(CYL,(1000,500),RLSE) //SYSIN DD *

LIBNAME DB 'OOOEDE.ZZZ.RESIDESC' DISP=SHR;

DATA TEMP; SET DB.VARDESC (KEEP=NAME); RUN;

LIBNAME DB CLEAR;

LIBNAME DB 'OOOEDE.ZZZ.RESIDESC' DISP=OLD;

DATA DB.JUNKDATA; SET TEMP;

PROC DATASETS NOLIST LIBRARY=DB; DELETE JUNKDATA; QUIT; RUN;
