DB2 SQL - How can I provide for a variable substitution in my SQL where clause?

Hi All,

I need to be able to substitute  two variables in this simple SQL code:

The JCL:
//SETVAR SET SSNODE=DBO1,DBOI=P1,DBOO=D2,
//           TRK=OG1,LOADIR=TEST,
//           PARMDIR=OGDBA,
//           PDBNAME='OG1DD%1',  <<-----Database name
//           PTSNAME='OG1SC%'       <<-----Tablespace Name

//SYSTSIN DD *
  DSN SYSTEM(DBO1) RETRY(3)
  RUN   PROGRAM(DSNTIAUL) PLAN(DSNTIB81) -
       LIB('SYS2.DB2.TEST.RUNLIB.LOAD') PARMS('SQL')
  END
/*
//SYSIN    DD *
  SELECT '-START DB('||DBNAME||') SPACENAM('||NAME||') ACCESS(UT)'  <<<------SQL
  FROM SYSIBM.SYSTABLESPACE
  WHERE DBNAME LIKE %PDBNAME
  AND NAME LIKE           %PTSNAME

//           PDBNAME='OG1DD%1',  <<-----Database name
//           PTSNAME='OG1SC%'       <<-----Tablespace Name


How can make this work?  I am getting errors every which way I try!
