In a script, how can I get repeated searches always to begin at the start of

If I precede the search with gg or :cursor(1, 1) I get E492, with 1G I get

I haven't looked closely at your mapping, but to use a normal-mode
command such as gg in a script, that is, as an ex command, you must
precede it with ":normal", as
:normal gg
Similarly, to use a function as an ex command, you must precede it
with ":call", as
:call cursor(1, 1)
See
:help :normal
:help :call
Another way to move the cursor to the first line of the buffer is to
simply put the number 1 on a line by itself, or in a mapping like
yours, as ":1<CR>".
HTH,

Yes, and why not use bar-separated commands? You _are_ running in
'nocompatible' mode aren't you? The following (untested) assumes that
this mapping definition is part of a script (of your vimrc, maybe):
map p$
\ :1d <Bar>
\ while @" != "" <Bar>
\ b # <Bar>
\ 1call search(@") <Bar>
\ s/^/$ / <Bar>
\ b # <Bar>
\ d <Bar>
\ endwhile<CR>
See
:help 'nocompatible'
:help :bar
:help map_bar
:help line-continuation
:help :d
:help :call
:help search()
:help :s
:help :map-<buffer>
:help 'runtimepath'
:help :autocmd
:help FileType
This would add a dollar and a space in front of the first line other
than the first in the alternate file which matches as a pattern any line
in the current file before the first empty line (or until end-of-file if
there is no empty line), and remove the matched lines (and the
terminating empty line, if any) from the current file. Repeated lines
cause repeated dollar-space insertion. If there is no match, add
dollar-space to the first line of the alternate file. If there are
several unmatched lines, add '$ ' that many times to the first line. If
a line in the current file starts with '$ ', the matching is done after
the changes for all preceding patterns have been made.
I mention :map-<buffer> and what I listed after it because if you need
this mapping for only one filetype (or a small number of them), it
should be defined with <buffer>, either in an after-ftplugin, or
alternatively at the FileType event but still with <buffer>.
Best regards,
Tony.
