caution: to use properly this script one must set up:
(i) in each html widow of this family:
(i1) its number with /<script type="text/javascript">win_nbr=?;</script>
(i2) back & forth links with: onclick="my_pop(??); return false;"
(dont' forget to change possible attributes 'href' & 'target' in each 'a' tag and/or add the 'back button' image -and its css selectors !-)
(i3) add the js script link to backnforth.js such as ... <script type="text/javascript" src="/HOME/backnforth_0.js"></script>
(ii) set the variables 'disp' below for each window
(iii) caution with 'nod' points such as 'prose_main.htm (can't just call the 2 backnforth_?.js scripts -> mixup leading to errors -in error console- in calling twice the vars & functs !? must implement all the dsip[?] below in just one js)
