*PREPBYMFD (SETMODE)

PLBCMP Only

*PREPBYMFD={ON | OFF}

This control specifies whether a PREPARE instruction should detect a MFD file description and allow the data manager to create the file.

When a *PREPBYMFD control is set to OFF, the PREPARE operation does not attempt to detect a MFD file descriptor and performs the PREPARE operation according to normal guidelines.

When set to ON, the action of a PREPARE instruction is to detect the presence of a MFD file descriptor and initiate a SUNDM PREPARE operation.

This same ability to control the action of the PREPARE instruction can also be controlled using the PLB_PREPBYMFD runtime keyword.
