Using bash to get Two variables in for-loop form two different lists

I'm working with bash and I have two lists:

Using the bash code below:

for f1 in AZU SJI IOP
do
    for f2 in A1 B1 C1
    do
        echo $f1 + $f2
    done
done

I get this result:

$ bash dir.sh
AZU + A1
AZU + B1
AZU + C1
SJI + A1
SJI + B1
SJI + C1
IOP + A1
IOP + B1
IOP + C1

I would like to get the result in this way

AZU A1

SJI B1

IOP C1

Define two arrays such that they have the same indices, then iterate over the indices of one array:

list1=(AZU SJI IOP)
list2=(A1 B1 C1)

for i in "${!list1[@]}"; do
  echo "${list1[i]} ${list2[i]}"
done

You could of course use paste, but since your lists are not in files, you might be interested in a solution without external commands:

set -- A1 B1 C1
for f1 in AZU SJI IOP
do  echo $f1 $1
    shift
done
