Here is a start which converts the first line of input to the
first three lines of output:
function! Convert(linenr)
let line = getline(a:linenr)
let result = []
for i in range(1, 3)
call add(result, substitute(line, '\$x', i, 'g'))
endfor
call setline(a:linenr, result[0])
execute a:linenr . 'put =result[1:]'
endfunction
With the cursor on the first line of input, following converts
the first line:
:call Convert('.')
Or, if the first line to be converted is line 12, this works:
:call Convert(12)
I suspect a complex :s/// with replacement \=... could do the
job, but the script is more maintainable and useful for related
work.
For the second change required, see:
:help function-list
:help nr2char()
