fScan Reference Manual, Chapter 2 (CmdLineOptions): copy
usage: -copy [mode] source target
The COPY command is used to copy information from one place to another. It can copy entire data files or copy specific aspects of one data set to another. The MODE argument determines what type of information is being copied.
Note: Except for FILE mode, the COPY command links the information to the new data set but it does not write that information out to disk files. Use the OUTPUT command to save changes to disk files.
