unable to return multilple values in perl

hello friends,

i have written one perl script.Which opens a file and search for some parameter's value and gets the status of these parameters. but while i am trying to return these value always i am getting false. Can any one please help me..
here is that function:
=======================

Code:

sub getParameterStatus {
open(FILE,"<$File");
if (grep{/parameter1=false/} <FILE>){
print " parameter1 is false Do you want to make it true \n";
$var1="true";
}
else 
{
print "parameter is already true \n";
}

if (grep{/parameter2=false/} <FILE>){
print " parameter2 is false Do you want to make it true \n";
$var2="true";
}

else 
{
print "parameter is already true \n";
}

if (grep{/parameter3=false/} <FILE>){
print " parameter3 is false Do you want to make it true \n";
$var3="true";
}
else 
{
print "parameter is already true \n";
}
close FILE;

return ($var1,$var2,$var3);

}

I think the $? returns 0 if the last issued command was successful and otherwise if not. But does anyone knows the value list that may be returned ? (or it is only zero/one ? ) Thanks in advance, Abrahao.

fopen

FOPEN(3S)																 FOPEN(3S)

NAME

       fopen, freopen, fdopen - open a stream

SYNOPSIS

       #include <stdio.h>

       FILE *fopen(filename, type)
       char *filename, *type;

       FILE *freopen(filename, type, stream)
       char *filename, *type;
       FILE *stream;

       FILE *fdopen(fildes, type)
       char *type;

DESCRIPTION

       Fopen  opens the file named by filename and associates a stream with it.  Fopen returns a pointer to be used to identify the stream in sub-
       sequent operations.

       Type is a character string having one of the following values:

       "r"  open for reading

       "w"  create for writing

       "a"  append: open for writing at end of file, or create for writing

       Freopen substitutes the named file in place of the open stream.	It returns the original value of stream.  The original stream is closed.

       Freopen is typically used to attach the preopened constant names, stdin, stdout, stderr, to specified files.

       Fdopen associates a stream with a file descriptor obtained from open, dup, creat, or pipe(2).  The type of the stream must agree  with  the
       mode of the open file.

SEE ALSO

       open(2), fclose(3)

DIAGNOSTICS

       Fopen and freopen return the pointer NULL if filename cannot be accessed.

BUGS

       Fdopen is not portable to systems other than UNIX.
