Is there a "clean" way to let my script know which letter is assigned?

I don't know, there is a switch for SHSUCDX to assign a specific letter though

it exists but it is the opposite of what I want to do

Not really. If you were to programmatically derive the next available letter, and then pass it to SHSUCDX, then you would know exactly what letter was assigned. You would already have your environment var for the rest of the script

ah ok, that's good reasoning

i can't find a way to do this in dos, would you know how to do it?

Easiest option is just to pick a drive letter that will always be free on every machine you use - X: or something. Then you don't have to mess around with finding the first available drive letter and communicating to the user what that letter happens to be.

If you really want a way of finding the first available drive letter I'm not sure you can do it just with a batch file. The NetWare DOS boot disk I use uses a program, dready.com, to inspect each drive letter to see if there is anything there. The utility is in nwdsk340.exe\NWDSK\CABS\UTILZ.CAB\bin along with a batch file, drd.bat, which inspects each drive letter outputting the results.
