MFILE keyword

The MFILE keyword specifies the DD name of the output file to which utility messages are to be written.

The output can go to a data set or to a printer, routed through the output stream.

MFILE is an optional keyword for the following statements:

  • ANALYZE statement of OPC
  • FPXCTL statement of ODE
  • REORG statement of OER
  • DMACPRT statement of ODM

Specifies the DD name of the output file for utility messages.

If the DD statement for the DD name specified by the MFILE keyword is not coded in the JCL stream and the DD name is not the default value, the utility ends with RC=8.

Default:
  • For FPXIN DD, FPXMFILE is used if the MFILE keyword is not specified.
  • For OPC with DASYSIN DD or for ODE with FPXCTL DD, SYSPRINT is used if the MFILE keyword is not specified. Even when the MFILE keyword is specified, utility messages are written to the SYSPRINT default file until the MFILE parameter is successfully processed.
