single output file with defined name

[Nguyen Huu Chuong]

Thank you very much for your answer. I did not even know where was the
manual. Since I wanted to get all the force in one file FILENAME
=work.frc is what I wanted
so I modified my input with

  &PRINT
    &FORCES
       &EACH
          GEO_OPT 1
       &END EACH
      FILENAME =work.frc
      ADD_LAST numeric
    &END FORCES
  &END PRINT

With ./work.frc I would have all step separated in different files.

Thank you again,

Nguyen Huu Chuong
