Specifies the copybook extension to be used when generating the complete copybook name for a DBD, MFS or PSB COPY statement.

Specifies the default file extension added to the input file name when no extension is specified.
ECHO
Controls the interaction with the DBDGEN, MFSGEN and PSBGEN utilities.

/PATH
Specifies the directory in which to save control blocks generated by MFSGEN.
SHRUPDT
Opens the output files for sharing so other tasks can read and update these files while the DBDGEN utility is running.
