Passing db path to \ l or .Ql using variable

Question

I am writing a q script that loads db in a specific path and does some processing on it. The db location is currently hardcoded in the script, but I want to pass the db path as an argument and get it to load from the path in a variable.

Currently it looks like this:

q) \l /path/to/dbDir        #Works

I realized that .Ql should allow us to do this with a variable, so I tried using the following in a script,

dbPath:`$.z.x 0
.Q.l hsym dbPath            #Fails

When launched with the / path / to / dbDir argument, the script always fails with some unreadable stuff and:

':/path/to/dbDir: No such file or directory

Can anyone help?
