Really!?) It seems to create an index and POINT to requested lines. TECO edited a file a page (delimited by ASCII FF) at a time. No backward movement. A co-worker used an editor on PDP-12 called SCROLL (I never mastered it.) It kept insertions in main memory. On overflow, it updated the file on block-addressable LINC-Tape (imagine peristalsis) and did a SEEK to where it had been. Undo?
