 Mine works too. This doesn't, tho:

 :map ^A ddjjjp       (A)

Obviously, I'm simply moving the  current line down  3 lines.
This gives the message "Cannot put inside global/macro".
But this DOES work:

 :map ^A 0d$P          

I am NO VI internals expert, but the most obvious  reasoning  is 
that VI can't scroll the screen from inside a macro. Armed with this
basic (maybe erroneous) assumption, I can get something like "(A)" 
above to work by the following:

 :map ^A ma3jo^[mb'ad$'bp        [...Aren't macros fun? :)]
         ^      ^

NOW - My questions:
 1. This works file on single lines, but simply terribly on entire
    paragraphs.  Does anyone have macros  (hopefully straightforward ones)
    to move Multiple lines/blocks from within a macro?   

 2. Does anyone have any ideas on ways to pass parameters to macros? Is there
    a version of VI that does?
