| 36 "Select buffer BUFNAME in the current window. | |
| 37 BUFNAME may be a buffer or a buffer name and is created if it did not exist. | |
| 38 Optional second arg NORECORD non-nil means do not put this buffer at the | |

| 41 WARNING: This is NOT the way to work on another buffer temporarily | |
| 42 within a Lisp program! Use `set-buffer' instead. That avoids messing with | |
