The traditional approach to pass environment variables upwards is to output a shell script and source that shell script from the calling shell:

eval "$(myvalues.pl)"

If you want to see and capture which shell variables a shell script sets up, a good approach is to run that shell script in a subshell and then output the resulting values. See for example Get default login environment and the comments to it, and also Shell::GetEnv.
