It would be far better to use this as a stream than to jam them all into shell variables. That is very inefficient and won't be portable.

Passing a array to a function, a basic feature in modern language, seems to be only possible in KSH. Not in BASH. Depite all my efforts I couldn't come to a solution. See the following examples:
It works perfectly in KSH:

Good grief so this should be easy. Passing an array as an argument to a function. Here is the sample code:
#/bin/bash
function foo {
local p1=${1}
local p2=(${2})
local p3=${3}
echo p1 is $p1
echo p2 is $p2
echo p3 is $p3
}

DIFF3(1) General Commands Manual DIFF3(1)
NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [ -ex3 ] file1 file2 file3
DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e.
the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ====
(====3). The following command will apply the resulting script to `file1'.
(cat script; echo '1,$p') | ed - file1
FILES
/tmp/d3?????
/usr/lib/diff3
SEE ALSO
diff(1)
BUGS
Text lines that consist of a single `.' will defeat -e.
Files longer than 64K bytes won't work.
