The "yank" will end JUST BEFORE the exact location of text X! marker "b".

The "yank" will end JUST BEFORE the exact location of text X! marker "b", if that is after the cursor; if it is before the cursor the X! "yank" happens as if cursor and marker were interchanged.

X X! In addition to the 26 named text buffers, 'vi' stacks deleted text X! in a set of 10 volatile buffers, generally called the "unnamed" buffers. By X! "volatile" I mean that the contents of these buffers change without the X! user's explicit direction. Actually, only the first of these volatile, X! delete buffers is really "unnamed"; it's the buffer that the most-recently- X! deleted text resides in, and from which the bare "p" and "P" commands work. X! The other nine delete buffers are reachable with the names "1" through "9". X! So if you delete some text in 'vi', the text you've just deleted is in the X! "unnamed" delete buffer and can be recovered with "p" or "P". If, without X! recovering that text, you now delete some more text, then the text you X! previously deleted is moved to delete buffer "1" and the most-recently-deleted X! text is now in the "unnamed" delete buffer. Keep deleting text, and the text X! you deleted the first time will advance from buffer "1" to buffer "2" and so X! on, until it gets to buffer "9", and if you delete more text after that, X! whatever is in buffer "9" is thrown away, and can no longer be recovered. X! Actually it can be recovered if you haven't written the file since you deleted X! the text: X :w temp X :e! X X--- 149,171 ---- X cursor position; if you use an uppercase "P", then the text is re-inserted X before your current cursor position. X X! In addition to the 26 named text buffers, 'vi' stacks deleted LINES X! in a set of 9 volatile buffers. By "volatile" I mean that the contents of X! these buffers change without the user's explicit direction. Another volatile X! buffer is called the "unnamed" buffer, in which the most-recently-deleted text X! resides, and from which the bare "p" and "P" commands work. This is the only X! buffer in which every piece of deleted text is put, the other nine buffers X! deal with complete lines only. They are reachable with the names "1" through X! "9", and hence are known as the numbered buffers. So if you delete some text X! in 'vi', the text you've just deleted is in the "unnamed" delete buffer and X! can be recovered with "p" or "P". If that text contains at least one line, X! it is placed into buffer "1" as well, whose previous contents are shifted into X! buffer "2" and so forth. Keep deleting text, and the text you deleted the X! first time will advance from buffer "1" to buffer "9". If you delete still X! more text, whatever is in buffer "9" is thrown away, and can no longer be X! recovered via the buffer mechanism. However, it can be recovered if you X! haven't written the file since you deleted the text: X! X :w temp X :e!
