Shell Programming and Scripting

This is what I did: 

Suppose: 

$ line="23|12|21"

$ eval $(echo "$line" | awk -F'|' '{print "V1="$1";V2="$2";V3="$3}')

$ echo $V1
23

$ echo $V2
12

$ echo $V3
21

Can there be a generic way such that if input line is having more numbers e.g. 

line="1|34|54|23|56|676|21|232"

we assign  each number to variable V1 to V8 as above but not assigning them as I did above(kind of hard coding). Please.

$ line="23|12|21"
eval $(echo "$line" | awk -F'|' '{for(i=1;i<=NF;i++) printf "V%s=%s\n",i,$i}')

$ line="23|12|21"
eval $(awk -F'|' '{for(i=1;i<=NF;i++) printf "V%s=%s\n",i,$i}' << "$var")
