Since you named your "keyword" kwd1, I have the suspicion that you
actually want to pass a keyword to EM, not a parameter. As Reimar
noted, it will probably be a matter of the definition of EM. My guess is

pro em,kwd1=kwd1

Then you will have to pass kwd1 as

em,kwd1=kwd1 *not* em,kwd1

I would recommend the online documentation: section on parameter passing
and keywords.

Martin.
