[Csnd] Writing and Reading from a .txt file

The Csound Mailinglist
1

Hello everybody,

i’m searching a opcode which allows writing to a .txt file with specific row number and line formatting.
Also i need a opcode for reading from a specific line and extracting some values from these lines.

Does something like this exists already in Csound?

Greetings,
Philipp

hi philipp -

i'd look into fprints for writing and readf for reading, but i don't know if this satisfies your needs ...

Hi!

Or can you use python opcodes pyinit, pycall etc - it could be way easier in python.

Hey all,

Both solutions don’t work for my needs.

Can i instead write to a ft and save the data from the ft as txt?
