UNIX, get environment variable

I have a ridiculous question due to a ridiculous problem. Normally if I want to get the contents of an environment variable in a UNIX shell, I can do ``` echo ${VAR} ``` Let's assume, due to my ridiculous situation, that this isn't possible. How do I get the contents of an environment variable to stdout, without someone who is looking at the command itself (not the output), see the value of the environment variable? I can picture the solution being something like `echo env(NAME_OF_VAR)` although I can't seem to find it. The solution has to work in sh. PS I can't write a script for this, it must be a built-in Unix command (I know, ridiculous problem).
