Is it possible to build variable names from other variables in bash? [duplicate]

Answer 1

for I in 1 2 3 4 5; do
    TMP="VAR$I"
    echo ${!TMP}
done

I have a general rule that if I need indirect access to variables (ditto arrays), then it is time to convert the script from shell into Perl/Python/etc. Advanced coding in shell though possible quickly becomes a mess.
