V_USE()         Opens a file on a local area network

Description:
  Opens a specified database file in the currently selected work area or
  notifies the user if unsuccessful.  The file can have an ALIAS
  specified as well as EXCLUSIVE use set on or off.


Syntax:     
  V_USE( <expC1>, <expL> [, <expC2>] )


Pass:       
  <expC1>  = Name of database to open

  <expL>   = .T. to open file exclusively
             .F. to open file in shared mode

  <expC2>  = Optional: ALIAS name to assign to the database


Return:     
  <expL>   = .T. if successful, otherwise .F.


Notes:      


Example:    
  DO WHILE whatever
     IF .NOT. V_USE("testfile",.F.)
        ac_msg[1] = "Unable to open file"
        ac_msg[2] = "Operation aborted"
        DISPMSG(ac_msg,2,"","")
        INKEY(5)
        EXIT
     ENDIF
     .
     .
     .
  ENDDO
  .
  .
  .


Usage:      
  V_USE() will attempt to open the specified database file in the mode
  in the specified mode.  If it is unsuccessful, a non-screen
  destructive message stating, "Waiting for busy network.  Press any key
  to abort." will appear on the screen and V_USE() will continue
  attempting to open the file in the mode specified.  If the user aborts
  the operation by pressing a key, V_USE() will return a logical value
  of false.  If V_USE() returns a value of false, it is your job as the
  programmer to abort the operation and recover properly.
