I have a problem with the translation of the following command in awk. In Shell the radiance-command work like that:

gensurf seitenwand rollerblind1 '-0.95*s' '0.046' '2.85-'$1'*t' 1 1

But I don't know how to deal with this command in system(). My skript looks like this. the importfile runde.txt is just a tabel with seven columns and numbers in it. I wanted to create a surface with different parameters getting out of the runde.txt file and written in the next course file *_adjust.rad:

(Toggle Plain Text)

cat runde.txt |awk '{
                               if ($5==2) {
                                                   dataname_v= " $1 "_" $4 "_adjust.rad
                                                   befehl1="gensurf seitenwand rollerblind1 '-0.95*s' '0.046' '2.85-"$7"*t' 1 1 > dataname_v"
                                                   system(befehl)
                                          }
                    }'

The problem is the '-sign, because in awk it is used for '{ and always when I am changing it the befehl-variable it is just printing the command with a replaced $7. Or it is telling me that the gensurf-command is used wrong because it is missing the end of the command...

Does anyone has an idea how to solve it? Maybe connecting strings?

Thanks a lot,
Ergy
