U_CLS   VARIABLE

 Function
  Allow reading and writing of the current users message clear screen flag.

 Type & Value
  BOOLEAN
  The current users clear screen flag status (TRUE or FALSE).

 Remarks
  This BOOLEAN is set with information from the current users record when
  the GETUSER statement is executed.  It may then be changed and written
  back to the users record with the PUTUSER statement.  Note that it is
  undefined until a GETUSER statement is processed and that changes are
  not written until a PUTUSER statement is processed.

 Examples

  GETUSER
  PRINTLN "Turning on the message clear screen flag..."
  LET U_CLS = TRUE
  PUTUSER
