Just tried the solution and it works perfectly!
Thanks, Again!

It works if that code is the main function. But in the full program that is only one of the functions and is not the main function.

This code runs as expected.
Strange. It does not for me. I even tried different compilers.
It simply does not ask for user input here where it is supposed
to:
```d
writef("Type the path to your USB drive: ");
string cont = readln;
writeln(cont); // there was no variable named "a"
```

Just noticed i forgot to put the proper variable name to the
input. Should not matter though. Also when I change it nothing
changes.
