Add AGAIN. There is no downside with using again, as far as I know, so I more or less use it always. I suggest you also add an alias

under myform procedure load
use mstr IN 0 again alias alist amstr 
use trans1 IN 0 again alias atrans1
use book1 IN 0 again alias abook1
use temp IN 0 again alias atemp
use book2 IN 0 again alias abook2
