Array from BASH, index from AWK

Question

Is there any possibility to get value from BASH array using index defined in AWK?

Bash:
table=(a b c d e)
instructions | awk " BEGIN {index=0} {print \"${table[**index**]}\"; index++} "

It sounds like you're asking us how to implement something that you shouldn't be doing. I recommend you post a different question asking how to do whatever the text transformation is that you are attempting, including sample input and expected output. — Ed Morton

You can do this but why?

table=(a b c d e); awk -vt="${table[*]}" 'BEGIN{n=split(t,a," "); for(i=1;i<=n;i++) print a[i]}'

a
b
c
d
e

you can do the array element access in bash directly as well.

Won't preserve embedded spaces in array elements.
