The  FMS/TEST  command  invokes the FMS Form Tester, which allows the
  user  to  test  the  form  as  though  it  had  been  displayed by an
  application  program.   The  output  device  must  be a VT52 or VT100
  compatible  terminal.   The default input file type is FRM.  There is
  no output from this command.
