*PREPBYMFD (GETMODE)


PLBCMP Only

*PREPBYMFD={value}

 

The *PREPBYMFD control reports whether the PREPARE instruction should detect managed file descriptor (MFDs).

 

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.

 

{value} is a previously defined Numeric Variable that receives the PREPBYMFD mode.

 

The {value} returned is one of the following:

 

Value

MFD file detection is ...

0

disabled (OFF).

1

enabled (ON) (default).
