The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

Null terminated or not, the string compare is done only with the shortest string which is not null-terminated (the literal *right* part of the comparison)
My point is that $str is futile and useless in this case

If getenv returns a null-terminated string then the statement should be:
If getenv('ENV_VAR') = %str('Literal value here');
I don't think that will work.
Justin's original code is correct
If %str(getenv('ENV_VAR')) = 'Literal value here';
getenv() returns a pointer to a null-terminated string. %str() returns the value of the string that the pointer is pointing to.
