I see the problem in this function.
First I tested it with for example a buffer containing
--- start of buffer
1
2
--- end of buffer
so swapping 1 with 2 gives
--- start of buffer
5816MHs
1
--- end of buffer
string-temp was 5826MHs and with these 3 lines
(goto-char (point-min))
(while (search-forward string-b nil t) ; string-b=2
(replace-match string-a)) ; string-a=1
string-temp is changed to 5816MHs and in the end, the last 3 lines do
nothing.
Any idea how to solve the problem?
