If the indices are necessarily successive integers:
links="A B C D"
index=0
for link in $links; do
index=$(( $index + 1 ))
something with $link and $index
If the indices are arbitrary:
links="1:A 4:B 7:C 10:D"
for linkinfo in $links; do
link=${linkinfo#*:}
index=${linkinfo%%:*}
something with $link and $index
