Subject: exec with string in variables?

Hi,

i have something like this and more in perl and would transform it to
ruby.
First i changed  system to exec and than the points  to plus , but the
strings which are in the scalar's seems
not be applied in the exec call , perhaps some special needs with
quoting!?


:perl
    foreach $line(@methoden) {
    system("$exe_path" .  "dti.exe -qb -t  -e$line  $dom_file
$train_file   $modell_string" . "$line" . ".dti");
    .................
    }

:ruby

methoden.each  do  |line|
exec("exe_path +  dti.exe -qb -t  -eline  dom_file train_file
modell_string + line + .dti")
.............
end

many thanks christian
