I would suggest to use a Print for each of the  plots, e.g.:

macro :=Module[{j},
Print["something"];
Print[plota];
Print["something else"];
Print[plotb];
];

this will not only be much easier to change but also reflect the 
original code better: it makes the display of the plot a side effect as 
it always was before version 5.

For new code, it of course it's of course better to take advantage of 
the fact that graphics-expressions that are return values now are 
rendered nicely in the frontend...

PS: you'll of course find similar questions and answers many times if 
you search the archive for messages from the time when version 6 came out...
