variable start values

Hi,
 Im writing a simple punctuation checker, I get the following message
when I try to execute this:

 "capital1 has not been assigned a value"

function check_for_punc_1(object x)
  boolean capital1
  if x[1][1] < 90 then
    position(2,1)
    puts(1,"GARBLE: [Sentence is not capitalized...]")
    capital1=0
  end if
    return capital1
end function
  
Do I have to initialize it first?
Because I have noticed that at other times, with similar things, I dont 
have to initialize...
For instance, if I go back to my function and add this line:

function check_for_punc_1(object x)
  boolean capital1
  capital1=1
  if x[1][1] < 90 then
    position(2,1)
    puts(1,"GARBLE: [Sentence is not capitalized...]")
    capital1=0
  end if
    return capital1
end function

The program will run fine...
Then I can actually go back and DELETE that line, and it will still run 
fine. I can save the program and run it as many times as I want
and it will run fine without that initialization.

Almost like the interpreter remembers when I initialized it...

Am I making sense? What is going on? I would just as soon NOT initialize 
the variable if my routine is going to set the value later.
But the question is:do I have to or not?
