The below DFSORT jcl can be used to dynamically generate a DSN RUN command to run an application program for db2. This makes it easy to code the DB2 subsystem name as a JCL symbolic and then run a program in the subsystem.
Code:

//*                                                     
// SET DB2SYS='????'                                   
//*                                                     
//* THIS WILL GENERATE THE DSN RUN PARM USING SYMBOLICS
//* PASSED IN AS PARMS.                                 
//* JP1=DB2 SUBSYSTEM, JP2=PROGRAM, JP3=PLAN           
//*                                                     
//SORT01   EXEC PGM=SORT,                               
//  PARM='JP1"&DB2SYS",JP2"??",JP3"??"'     
//SYSOUT    DD SYSOUT=*                                 
//*SYMNOUT   DD SYSOUT=*
//SYSIN     DD *                                       
 SORT FIELDS=COPY                                       
 OUTFIL FILES=OUT,REMOVECC,                             
   HEADER1=(' DSN SYSTEM(',JP1,')',/,                   
            ' RUN PROGRAM(',JP2,') PLAN(',JP3,')')     
//SORTIN    DD *                                       
 END                                                   
//SORTOUT   DD DSN=&&DSNRUN,
//  DISP=(NEW,PASS),SPACE=(TRK,(1,1))                 

If the program requires a parm then it is easy to add another symbolic JP4 to the parm and modify the sort control statement.
