I'd only expect that to work with the bash shell and only if it's not in POSIX mode and variable names and values don't contain newline characters and name doesn't contain spaces. The OP specifically asked for a POSIX shell solution. If you're going to use a bash-specific solution, you might as well use compgen -e

This works for the case where variable values have newlines & spaces, that's the case that I wrote this for... I didn't realize you could have newlines in a variable name. It is an example for bash, because the OP provided an example for bash that didn't work, and this snippet does.
