Does anyone know if there is anything special about this dd?? I've searched the forum, the JCL manuals, GOOGLE, the IKJEFT1B utility, everywhere I can think of. The code I'm questioning is below:


//STEP2 EXEC PGM=IKJEFT1B,COND=(4,LT),DYNAMNBR=20,
// PARM=('%RUNDB2 SSID(&SSID) PGMNAM(CUBCP100)PLANNM(BCP100&PLSFX)',
// 'RUNPRM(&PGMVERA.&RUNDATE.)')
//SYSPROC DD DSN=SCLMTECH.PROD.SYSPROC,DISP=SHR
//WCODF010 DD DSN=&I1HLQ..KSDS.WCODF010,DISP=SHR
//ENQUEUE DD DSN=MCU.CCPD100.SINGLE.THREAD,DISP=OLD,
// VOL=REF=RESVOL

The funny thing about this dsn is that it doesn't exist & the RESVOL is
a variable that converts to our sysres volume. Does anyone know how the system can set a dd to a disp of old on a dsn that does not exist????
