Quite similar to PHP's print_r you can retrieve all data in a specific lua table or variable.

Code

xtab={}
xtab.foo={1,2,3}
xtab.bar={L=1,U=2,A=3}
> print_r(xtab)
--[[
  [bar] => table: 0033DAA0 {
             [U] => 2
             [L] => 1
             [A] => 3
           }
  [foo] => table: 0033DAA0 {
             [1] => 1
             [2] => 2
             [3] => 3
           }
]]
