Location of function declaration??

[Mike Crowe <mike@...>]

Hi folks,

Sorry to pound with the group with n00b questions, but here's another one.

I'm parsing a text file, and wanted to declare a function to print the 
table I'm building.  Code is below. 

Here's the question:
I see I have to declare function before using.  However, it appears that 
the function executes once as the system runs.  I had to put in the 
statement below "if tab[1] then" to catch the first run with a nil.  
Shouldn't the function only been called when I call it below?


t = {}
index = 0

local printTable
function printTable(tab)
   if tab[1] then
      ...
   end
end

for line in io.lines("test.txt") do
   --build table here
   printTable(t)
end

TIA
Mike
