U_VER   VARIABLE

 Function
  Allow reading and writing of the current users verification string.
  (if the SysOp has enabled user verification)

 Type & Value
  STRING
  The current users verification string (25 characters max).

 Remarks
  This STRING is filled 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 empty until a GETUSER statement is processed and that changes are
  not written until a PUTUSER statement is processed.  Additionally, it
  will only have meaningful information if the verification PSA is
  installed.  The existence of the verification PSA may be checked with
  the PSA() function.

 Examples

  STRING s
  IF (PSA(2)) THEN
    GETUSER
    PRINTLN "Enter verification information"
    INPUT "",s
    IF (s <> U_VER) HANGUP
  ELSE
    PRINTLN "No verification information available"
  ENDIF
