Re: how to move x inside a function?

Here is the whole script.
Encode selected text as html entities.

function Encode(str)
let out = ''
for i in range(strlen(a:str))
let c = a:str[i]
let n = char2nr(c)
let r = Urndm(0,9)
if r > 6 && c != "@" && c != "."
let e = c
elseif r > 3
let e = printf("&#x%x;",n)
else
let e = printf("&#%d;",n)
endif
let out = out . e
endfor
return out
endfun

function ReplaceWithEncoding()
let save = @@
normal! gvy
let @/ = @@
'<,'>s//\=Encode(@@)/
normal! `<
let @@ = save
endfun

vmap <F5> :call ReplaceWithEncoding()<cr>
