Alias()

I do the following in one of my modules

sele 909 use (ltable) alias Junk1 Excl

If I issue wait window alias(), it returns Junk1

If I use (ltable) alias "Junk1" Excl, it returns Junk1 as well

Is this normal?

I ask because I have a client who consistently ends up with an error variable code not found when I know for sure the table has a field called Code, and I am trying to confirm the underlying table is indeed Junk1
