<h3>File to receive output (OUTFILE)</h3>

<p>Specifies the library and database file to which the output of the command is directed. If the file does not exist, this command creates a database file in the specified library, using file QAPYDMPMEM in library QSYS as a model. If the file is created, the public authority for the file is the same as the create authority specified for the library in which the file is created. Use the Display Library Description (DSPLIBD) command to show the library's create authority.
