The following JCL will be run on opc. I want to know the difference
between &MNTH and %CMM ?
Code:

//SYSUT2  DD  DSN=AU0ENC.BE.EXTRACT.&MNTH%CMM.,                         
//         DCB=(RECFM=FB,LRECL=80,BLKSIZE=32720,TRTCH=NOCOMP),         
//         LABEL=(1,SL),STORCLAS=SCNOSMS,                             
//         UNIT=3490,VOL=(,RETAIN,SER=CMDX01),EXPDT=98000         

&MNTH <== will be replaced by variable defined at opc.     
%CMM <==  what's meaning? what difference with &MNTH ?

ANDY,

MNTH is a your variable defined to OPC.

CMM is a 2 byte date related jcl variable which gives you Current month in MM format

Check this link for the definition of other date related JCL variables in OPC
