Hi, I'm trying to add (back slash) in front of any " mark.

event f 1 0 524288 1 "Macintosh HD:loop.aif" 0 0 0

to external called Csound~. But when I send this message

to Csound~, "" didn't get transfered so I get an errors.

it works if I put in front of " then everything is fine

but I don't want(and I shouldn't for stand alone issue) do

it manually. So how could I add to " automatically?

regexp and careful use of escaping. You're working with 'active' 

characters ["], so it's going to look messy. You may also need to 

compensate for max-syntax-related transformations after output too.

If you're constructing the initial message yourself, then sprintf should 

work to combine the components and add the necessary syntax. You will 

still need to keep in mind what happens to the message after it 

re-enters the normal max syntax universe.

You cannot, generally. This goes for any other programming language 

that requires you to escape quotes. There is no way to process a 

message/string with an unescaped quote in it because, to the 

language's parser (the thing that turns your code/path into something 

that makes sense to the language), the quote is syntax. You need to 

escape it to make it part of the message. In Max, quotes are used to 

designate symbols (otherwise you'd have to escape every space in a 

If you need to escape tons of messages like this to load into Max, 

I'd suggest you do it in another program and then stick them into 

Max. The other alternative is not putting in any quotes at all, and 

then inserting them escaped later on by finding all of the bits with 

non-numeric characters after "event f" and lumping them together. 

This seems like a waste though -- Ideally you want to have it done 

upfront. Max is not properly equipped to deal with this.

Assuming you have a file full of lines that need quotes to be 

escaped, you can do something like this in Io (www.iolanguage.com):

OutputFile := File clone openForUpdating()

    OutputFile write(line asMutable replaceSeq(""", "\""))

back slash question.
