Arguments

Alternatively, the work area pointer as passed from internal functions of the RDD system can be specified.

<lBof>

This is a logical value specifying the BoF() flag for the work area.

Description

UsrRdd_SetBof() is used to set the Begin-of-file flag to .T. (true) or .F (false). A user-defined RDD is not required to re-implement the Begin-of-file flag since it is incorporeted in the user-defined RDD system.
