How to transmit the name of signal?

You mean, you wish to pass a Signal to a function/subroutine by name? Hm... I don't recall ever attempting that myself, but system functions like PULSE will work on signal names, as well as $OUTs. So it might be possible to pass a Signal by name and allow the function to manipulate it, as long as it was passed with :OUT rather than :IN.

$OUT_C[] requires an integer which is the index value of your output
i think there are only two options to this, pass index or pass name of the signal

DEF sig( )
  signal test_o $out[22]
  decl siginf s 


  ; example1 - pass name 
  test_o=false
  sig_on("test_o")




  ; example2 - pass index
  test_o=false
  s=get_sig_inf("test_o")
  sig_on2(s.idx)


END


def sig_on(sig_name[]:in)
  decl char sig_name[]
  decl siginf sig
  sig=get_sig_inf(sig_name[])
  $OUT_C[sig.idx]=TRUE
end


def sig_on2(sig_index:in)
  decl int sig_index
  $OUT_C[sig_index]=TRUE
end

You can pass a signal to a function, by treating it as a bool reference in your function:

Def my_function(my_signal:out)
bool my_signal
...
...
End

I have done this, and it works.
Was this what you were looking for?

That will transmit value, not the name of the signal...

I guess you're right. Would it be possible to solve the problem by making two signals?

SIGNAL O_TEST $OUT[50]
SIGNAL O_TEST_C $OUT_C[50]

That would then require that one signal is used in one case, and the other signal in another case. Maybe not the most elegant solution. But would it work? I guess my question is: Is it possible to make a signal which is linked to $OUT_C?
