Msg: SPELL in U2

Hi everyone.

Can anyone run me through the use of the SPELL routine in U2? I follow the somewhat cryptic instructions in XYWWWEB.INF and end up with the to-be-checked file and SPELL.TMP (listing the questionalble words) in adjacent windows. What to do from there is unclear to me. If I re enter spell while viewing SPELL.TMP, a prompt declares, "call subject file in adjacent screen." Attempting that, I get a prompt query about do I want to re-open an already open file. There is no obvious task to complete when switching between the two windows, back and forth, nothing to do. I am not able to figure this out by reading, and re-reading, the help file. Looking for help, with thanks for this great list,
