If getenv returns a null-terminated string then the statement should be:
If getenv('ENV_VAR') = %str('Literal value here');

I'm afraid I'm not familiar with a "zero terminated string"
My intended use is this:
If %str(getenv('ENV_VAR')) = 'Literal value here'; Endif;
I believe getenv() returns a null-terminated string.
Thanks

For the purposes of converting a zero terminated string into an RPG VARCHAR, it is not inefficient. It has never been inefficient. This is what it was designed for.
For other purposes, though... ? Well, it depends on the purpose.
