GRETL Scripting: Is it possible to user OPEN with a string variable without $workdir?

Question

So I'm doing a GRETL script where the users writes his Operating System (Windows/Linux), his path to a gretl workdir and the .gdt file to open (saved from a previous exercise).

This passes on string variables. One of such variables is gdt_file which before opening should be /path/to/file/file.gdt

Now, reading GRETL documentation, the open command will by default look for file.gdt inside the $workdir.

Now, what I want to do is open gdt_file, but of course it doesn't work because it's looking for gdt_file.gdt inside $workdir, instead of open /path/to/file/file.gdt

I've played a bit with it, but I'm unable to find a workaround, IDK if this is even possible, the documentation isn't very clarifying.

Thank you for your time.

here's the thread with the reply from the Gretl team, in case anyone is wondering: https://sourceforge.net/p/gretl/bugs/247/

Basically, use command "@variable" as in string substitution in the gretl guide.
