Answer / ankita
TCP first validates terminal using TCT.Task Control Program
(KCP) uses the Program Control Table(PCT) for identifying
and intializing a transaction.Program name will be there in
PCT entry.Program Control Prog.(PCP) uses the PPT
(Processing PRog. table) for validating the program name.In
similar way, PCP&FCT,JCP&JCT , etc. works
