There is the main buffer that you are viewing called file1. Here you run a lisp function which is supposed to write some text of the file or in a variable to another file called file2. I have looked and found this function: (append-to-file START END FILENAME) This function is only good enough to copy selected text from file1 to file2, BUT I want a function that copies value of a string variable str-var into file2 or some other string. Basically, I want a generalization/modification of the command "insert" to append which takes a filename as an argument and appends a given string over there. I know one dirty workaround is to insert the text in file1, and then append-to-file into file2 and then remove it from file1. Is there a faster or cleaner approach ? This has to be done a lot and one wants something faster than writing, copying and erasing. append-to-buffer is an interactive compiled Lisp function in `simple'. (append-to-buffer BUFFER START END) Append to specified buffer the text of the region. It is inserted into that buffer before its point. When calling from a program, give three arguments: BUFFER (or buffer name), START and END. START and END specify the portion of the current buffer to be copied.
