The problem seems not to come from taking brackets into account or not
(i tried many combinations before reposting), but from the keyword
'top'.

If i omit it :
graphics text {0 0 0} "Test" size 24
instead of :
graphics top text {0 0 0} "Test" size 24

I get the error :
expected integer but got "text"

But still my goal was to produce sub-trajectories out of a bigger one
based on distances/angles/dihedrals criterias, Eduard Schreiner gave me
important steps but it if a different goal, out of my primary purpose.

Any hint ?
