thanks Matthew, but this does not help.

there is a difference between  echo ${var}  and  ${var}  !!!

$ TOOL=3D'find . -name "" '
$ echo $TOOL
find . -name ""
$ set -x ; ${TOOL} ; set +x
+ find . -name '""'
+ set +x
$


continuing on this, it seems that  eval  might help me

$ set -x ; eval "${TOOL}" ; set +x
+ eval 'find . -name "" '
++ find . -name ''
+ set +x
$

well, the dbl.quotes get _replaced_ by single quotes,=20
which seems to be equivalent and not to trouble further.

I have to see wheter I can deploy that in my script,
but I'm not happy: this involves the discipline to think=20
about and decide whether an eval is necessary bevore a=20
command.
I don't like to run a collection of variants for how commands=20
need to be called...
then using eval systematically at every command call feels
clumsy saying the least.

I'll throw an eye on that "Unix Power Tools" book.
