Creating a duplicate to-file member

 

You can create duplicates to-file members without doing the copy file action again. When your application requires an exact duplicate of the records in the to-file member (if either the from-file is empty or contains data), an alternative solution is to use the Clear Physical File Member (CLRPFM) command:

CLRPFM FILE(X) MBR(XYZ)
CPYF FROMFILE(Y) TOFILE(X) TOMBR(XYZ) +
     MBROPT(*ADD)

Because MBROPT(*ADD) is specified, the CPYF command completes normally even if there is no data in file Y. MBR(XYZ) in file X contains an exact duplicate of the records in the member in file Y.
