[Csnd] Saving score lines to text file

I want to save some parameters of my Csound program as a list of score lines
to a text file, so I can reset them later with the scoreline opcode. It's a
kind of system of named presets, saving only the parameters that are
relevant to the algorithm.
So I did the following:
instr save_params
S_FileName strget p4
S_Msg sprintf "i \"set_audio_file\" 0 0 \"%s\"\n", gSAudioPath
fprints S_FileName, S_Msg ;fprints doesn't support strings!
fprints S_FileName, "i \"set_params\" 0 0 %g %g %g %g\n", \
gkPitchScale, gkTimeScale, gkGrainSize, gkOverlaps
turnoff
endin
It works the first time, but when I call "save_params" again with the same
file name, the score lines are appended to the actual file instead of
creating a new file.
When I stop Csound and restart it again, a new file is created, replacing
the old one.
I would like to have this behavior every time.
Is there a solution with other opcodes (that accept to write score lines
containing strings) ?

Is there a close file opcode you can call before trying to write to it again? On Sun 27 Oct 2019, 11:08 Bernard Geyer, <micamusic2@gmail.com> wrote: I want to save some parameters of my Csound program as a list of score lines |

I tried to put
iHandle fiopen S_FileName, 1
on the beginning, and
ficlose S_FileName
on the end.
It doesn't work.
fiopen / ficlose seems to work only with fouti but fouti doesn't accept
string arguments

Not as far as I know, but you can always call system commands from csound with system_i i_ system_i "rm file.txt" ;; (if you're on mac/linux) On Sun, 27 Oct 2019 at 12:51, Bernard Geyer <micamusic2@gmail.com> wrote: And that does not work either: |

And that does not work either:
instr save_params
S_FileName strget p4
iHandle fiopen S_FileName, 1
S_Msg sprintf "i \"set_audio_file\" 0 0 \"%s\"\n", gSAudioPath
fprints iHandle, S_Msg ;fprints doesn't support strings!
fprints iHandle, "i \"set_params\" 0 0 %g %g %g %g\n", \
gkPitchScale, gkTimeScale, gkGrainSize, gkOverlaps
ficlose iHandle
turnoff
endin
Is there an opcode to delete a file ?

SORRY !!!!!
ficlose works !!!
I used the wrong version of save_params. ( I have one with gui, and one with
text)
