Yes, that would work:

        data = "tool=curl"
        data = "${data}&ssl=yes"

... and for reading environment variables as well:

        data = "home=${HOME}"

Well, wouldn't it be even better if the command line switch would allow the
format to be VAR=CONTENTS ? Like:

        curl --argument name=daniel --argument curl=yes -K config

Hm, but that comes very close to being unnecessary since the variables could
just as well be set in environment variables in this case (and save me from
lots of work :-):

       name=daniel curl=yes curl -K config (sh/bash syntax)
