[Help-bash] array issue

[Bill Gradwohl]

I'm stumped. Can anyone please explain this:

declare -a regex
echo highest subscript of regex=${#regex}
   regex[${#regex}]='[_a-zA-Z0-9][[:alnum:]]*[[:blank:]]*()'
echo highest subscript of regex=${#regex}

Produces:
address@hidden junk# ./test
highest subscript of regex=0
highest subscript of regex=38



address@hidden junk# bash --version
bash --version
GNU bash, version 4.2.20(1)-release (x86_64-redhat-linux-gnu)
