Hi Shaun,
You are doing it right. The 'getenv' modulefile command has a specific
behavior when modulefile is evaluated in display mode: it returns the
environment variable name prefixed by the '$' sign.
So 'getenv' should not be used in conjunction of commands that requires the
environment variable value if one want to display the modulefile without
error.
On the next version (5.1), I have added a --return-value option to getenv
[1] to tell this command to also return the environment variable value when
evaluated in display mode.
Best regards,
Xavier
