Using the syntax $() for both functions renders also the order above unusable 
(here FSTONES will get reset by assemble_fam2 then). Like $() will revert an 
unrelated variable to a former state.

There also seems to be difference between using run_aliases or issuing both 
commands by hand.

Using `` for both functions looks like being safe though and covers all cases.
