The example near the top of Sobell, page 486, demonstrates a way to put a variable in the environment of a script you are calling without declaring the variable in the interactive shell you are running. Use this technique to assign a value to myvar, place it in the environment of echomyvar, and run echo- myvar. After running the script, is myvar set in the interactive shell?
