How can one delete all variables currently in memory in KDB/q?

Instead of listing variables manually (I have many of them) like so:

delete a,b,c from `.

I would like to do something like these (the commands below do not work):

delete (system "v") from `.
{delete x from `.} each system "v"

Thank you for your help!

You can use functional form to accomplish this:

q)a:1
q)b:2
q){![`.;();0b;enlist x]}@'system"v"
`.`.
q)a
'a
  [0]  a
