and another (in git), with an INF score:

  csound -d -m0 -odac --orc /dev/stdin <<'EOF'
  sr = 44100
  ksmps = 64
  ...
  turnon 1    ; or alwayson
  instr 1
  ...
  endin
  ...
  EOF

and more

  make_orcfile_script | csound -odac --orc /dev/stdin         # inf score

  make_csdfile_script | csound /dev/stdin

  csound -odac --orc <(make_orcfile_script)                   # inf score 

  csound <(make_csdfile_script)

  csound -d -m0 -odac /dev/stdin <<'EOF'
  <CsoundSynthesizer>
  <CsInstruments>
  sr = 44100
  ...
  EOF

The extension of the file is not important. The default with a single file is
csd file. --orc single_file is an orchestra with an infinite (lies, ~25367 years)
score file.
