running a batch script from thumb drive

[calmchess21]

Hi I'd like to run a batch script from my thumb drive so for it to find the path to my .exe which exsists on the thumb drive i'd have to write something like f:\my.exe....the problem is as follows.

I don't know what the drive letter will be since each user could have multiple harddrives or other devices....so how do i tell the batch file how to find the path to my jump drive without changing the scripts code?

if it's on the same drive, could it work without drive letter at all?
just
my.exe
