Please use $(...) notation. We try to write the bash code so that it is also easy to read.

BTW, you could probably do make this code simpler by using something like 

```bash
while IFS== read key value ; do
    case "$key" in
        gv_ro) SESAM_BIN_DIR="$value" ;;
        gv_rw) SESAM_VAR_DIR="$value" ;;
    esac
done <"$SM_INI"
```

Shorter, faster and easier to read. The trick is to use and IFS of `=` and read to split the ini file into key/value pairs.
