I'm glad I'm on this forum, I know exactly what you did wrong mr.

I checked the documentation and it seems that, you assumed the 
wrong syntax for "environment.opIndexAssign()"

The correct syntax is:
>environment.opIndexAssign("Some Random Value Here", 
>"variableName");

And not this one:
>environment.opIndexAssign("variableName", "Some Random Value 
>Here");


Take a look at this documentation once more:
https://dlang.org/library/std/process/environment.op_index_assign.html
