argument ranges depending on earlier arguments

[Ozgur Akgun]

Hi,

Is it possible in GNU Parallel to have argument ranges depend on earlier
argument values? For example, how would one translate the following nested
for loop to use GNU Parallel?

for i in {1..3}; do
    for j in $(seq 1 $i); do
        echo $i $j
    done
done

Thanks,
Ozgur
