READKILL()
 Return, and optionally set, whether the current READ should be exited
------------------------------------------------------------------------------
 Syntax

     READKILL([<lKillRead>]) --> lCurrentSetting

 Arguments

     <lKillRead> sets the READKILL() flag.  A value of true (.T.)
     indicates that the current read should be terminated, and a value of
     false (.F.) indicates that it should not.

 Returns

     READKILL() returns the current setting as a logical value.

 Description

     READKILL() is a Get system function that lets you control whether or not
     to terminate the current READ.

     Unless directly manipulated, READKILL() returns true (.T.) after you
     issue a CLEAR GETS (see the CLEAR GETS entry ) for the current READ;
     otherwise, it returns false (.F.).

     By accessing the function directly, however, you can control the
     READKILL() flag with its function argument and use it to create new READ
     layers.
