Why don't you use arrays?

An example how to use arrays and "dynamic variables" if you persist to use that:
Code:
set $(awk 'BEGIN{FS="|"};{print NF}' ffvldtn_test.txt)

n=1

for i in $@
do
  arr[$n]=${i}		# fill array
  eval "var_${n}=${i}"	# fill dynamic variable
  n=$(( $n + 1 ))
done

echo arr[1]
echo arr[2]
echo arr[3]
echo arr[4]
echo arr[5]

echo $var1
echo $var2
echo $var3
echo $var4
echo $var5
