The command line you describe takes all the output from ls and passes it 
as a single command line to "genisoimage -o test.iso". In other words, 
if your current directory contains:

    file1   file2   file3

then your command line results in:

    genisoimage -o testi.iso file1 file2 file3

To do the same thing in gambas, you must construct a string from the 
file you want, then pass it to SHELL, but without opening that process 
for input or output. Or, may be, you want to get its output to see how 
it went, like:

    SHELL "genisoimage blah blah blah" TO whathappened
    taResult.text = whathappened
