I am re-reading your question. Is what you want this:

line1_of_file/output19
line1_of_file/output20
line1_of_file/output21
line1_of_file/output22
line2_of_file/output19
line2_of_file/output20
line2_of_file/output21
line2_of_file/output22

In that case it is simply doing:

cat filename | parallel seq 19 22 \| parallel -I @ echo {}/output@

which should work in any shell.
