I can't understand the below code in a JCL. What is the below language?
Can you recommend to me a good book about this language?
Code:
SIGNON USERID=(Y) ESF=YES
SUBMIT PROC=MODEL90 SNODE=UNIX.TCMINDU1.P HOLD=NO CASE=YES -
SNODEID=(USERID,PASSWORD)
&FROM=PNODE
&TO=SNODE
&DSN01=PV5240A.DB2.CARR.MKT.DTL
&OUT01='/DATASTAGE/DATA/CLSI_REQMNT/LOSSDB/CARRTST.DAT'-
&OPDISP=(RPL)
SIGNOFF
