Please can someone help to return the array elements from a function. Currently the problem I face is that tempValue stores the value in myValue as a string while I need an array of values to be returned instead of string.

I try to get a number of elements in an array, using dynamic array name.
I need the array name to be dynamic.
The array name is constructed as 'inf_ln_$nmb', where $nmb is a file line number
So, say I have the arr 'inf_ln_4':

s3get
S3GET(1p) User Contributed Perl Documentation S3GET(1p)NAME
s3get - Retrieve contents of S3 items
SYNOPSIS
s3get [options]
s3get [options] [ bucket/item ...]
Options:
--access-key AWS Access Key ID
--secret-key AWS Secret Access Key
Environment:
AWS_ACCESS_KEY_ID
AWS_ACCESS_KEY_SECRET
OPTIONS --help Print a brief help message and exits.
--man Prints the manual page and exits.
--verbose
Output what is being done as it is done.
--access-key and --secret-key
Specify the "AWS Access Key Identifiers" for the AWS account. --access-key is the "Access Key ID", and --secret-key is the "Secret
Access Key". These are effectively the "username" and "password" to the AWS account, and should be kept confidential.
The access keys MUST be specified, either via these command line parameters, or via the AWS_ACCESS_KEY_ID and AWS_ACCESS_KEY_SECRET
environment variables.
Specifying them on the command line overrides the environment variables.
--secure
Uses SSL/TLS HTTPS to communicate with the AWS service, instead of HTTP.
ENVIRONMENT VARIABLES
AWS_ACCESS_KEY_ID and AWS_ACCESS_KEY_SECRET
Specify the "AWS Access Key Identifiers" for the AWS account. AWS_ACCESS_KEY_ID contains the "Access Key ID", and
AWS_ACCESS_KEY_SECRET contains the "Secret Access Key". These are effectively the "username" and "password" to the AWS service,
and should be kept confidential.
The access keys MUST be specified, either via these environment variables, or via the --access-key and --secret-key command line
parameters.
If the command line parameters are set, they override these environment variables.
CONFIGURATION FILE
The configuration options will be read from the file "~/.s3-tools" if it exists. The format is the same as the command line options with
one option per line. For example, the file could contain:
--access-key <AWS access key>
--secret-key <AWS secret key>
--secure
This example configuration file would specify the AWS access keys and that a secure connection using HTTPS should be used for all
communications.
DESCRIPTION
Retrieves S3 items, and outputs them to stdout.
BUGS
Report bugs to Mark Atwood mark@fallenpegasus.com.
Occasionally the S3 service will randomly fail for no externally apparent reason. When that happens, this tool should retry, with a delay
and a backoff.
Access to the S3 service can be authenticated with a X.509 certificate, instead of via the "AWS Access Key Identifiers". This tool should
support that.
It might be useful to be able to specify the "AWS Access Key Identifiers" in the user's "~/.netrc" file. This tool should support that.
Errors and warnings are very "Perl-ish", and can be confusing.
Trying to access an item that does not exist or is not accessable by the user generates less than helpful error messages.
Trying to retrieve a bucket instead of an item is silently skipped.
TODO
option to write to files instead of stdout
option to write to paths instead of stdout
option to write to a tar file stream, for multiple items
option to write extended file attributes based on S3 & HTTP metadata
option to have a progress bar
