U_PWD   VARIABLE

 Function
  Allow reading and writing of the current users password.

 Type & Value
  STRING
  The current users password (12 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.  A mask of valid
  characters that may be used in the U_PWD variable is available via the
  MASK_PWD function.

  INPUT "Enter Password",s,@X0E,12,MASK_PWD(),UPCASE
  GETUSER
  IF (s <> U_PWD) THEN
    PRINTLN "Sorry, hanging up"
