To use an environment variable at a command prompt or within a batch file, the environment variable should be enclosed in %s such as:
echo %path%This should output the value of the PATH environment variable. No need to get Windows Power Shell involved. It should be just that simple.

Greetings. I am on windows 7 and am trying to run some batch commands, for which I need to know what is the syntax to get at the value of an environment variable? I try %PATH%, %PATH, and even $PATH like in unix, but it all fails to expand the value of the variable. Since power shell apparently supports such unix-esque names as ls and pwd, I am perplexed how to get it to pick up arguments. BTW: echo $PATH prints nothing, whereas the % signs just get passed through as if it is not a special syntax, as in a dos window. So I suppose I'll get rid of power shell and use the dos window where the args are predictable. Now in the time it took to type this I could have done that. Comments welcome.
