Your patch breaks when you have a line with a comma in your text file. Such a line is broken into two lines. Regarding your insistence to do that task with Pd, I think you should reconsider your reasoning. Pd is not particular strong in string processing, exactly because of reasons like this. IMHO, your best bet is to not use character representation at all in Pd which is probably the only safe way not to get in conflict with special characters in Pd (at least as long as there isn't a proper way to escape them). See attached example with [mrpeach/binfile] -> [text3d]. This example doesn't do any processing at all, it only passes the data "untouched" to [text3d]. If you really want to do some processing, I'd probably do that outside of Pd. There are plenty of ways to roll your own external class with any of several scripting languages (bash, lua, python, tcl, etc.). I'd probably offload all the real string processing to such an external. Roman
