Unfortunately, the outcome seems to be the same
transposed array that I was trying to avoid.
What "transposed array"?
The function I posted (as fixed below) copies an array to a different name; there is no change to any part of the array.

I would have thought it would have worked as it's
the same method used to return an array from the
'load' function which works as expected. However,
the array being returned from the 'load' function isn't
a passed variable and is not reassigned.
What "load function"?

The problem seems to specifically originate from the
assignment of an array to array regardless of
method used to assign them, as it would seem.
What problem?

An article did describe the reassignment of arrays
and that it does automatically strips white space from
an array which I find is a bad policy enforcing limitations
on the coder.
The reassignment of an array (as done in the function I posted) doesn't strip anything.
CORRECTION: OOPS! Yes it does; the function should have read:

The alternatives that I've also tried are:
function pointers,
referenced variables i.e. ${!ARRAY},
changing the IFS variable to '' ,
and the alternatives that I'm considering:
regex to reconstruct the lines of the array
by using an end of line character,
and global variables (last resort).
The passing of an array to a function is the foundation
of my library, any solution would ideally fit to as fewer
lines as possible as it's repeated throughout every function,
unless I can reuse the 'array_assign' function within another
function with it executing correctly.
Any further suggestions would again be appreciated.
On further investigation, the function above will work in bash 3.0 and later. Empty elements will be stripped in earlier versions of bash.

Reason: Fix function
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:

Hello,
basically what this script is supposed to do is showing a list of hosts that is given a number, that you will be able to choose from a list.
A check is made to verify that the chosen number is within the array and this is where things go bad and I don't know why, bizarre.

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
}
d1=data1
d2=data2
a=(bat bar baz) (2 Replies)
Hi,
I'm trying to write a bash script that takes a file and passes each line from the file into an array with elements separated by column.
For example:
Sample file "file1.txt":

3 name3 c third
and have arrays such as:
line1 = ( "1" "name1" "a"... (3 Replies)
