Hello, my problem is simple & I searched a lot but I couldn't find anything about it:
Basically I'd like to pass $i to a variable, $i being the positional variable; but it is unknown in the beginning so I can't do it like eg. myvar=$3, it HAS to be the "i"..
First, I tried myvar=$($i) (because $i is the number of i (ex 5), and not the positional variable ($5) so we would need in theory another $ to get to the positional variable), doesn't work
I tried this also, though I'm not sure if it's correct:
(in my code, i'd like myvar to get the (2+$a) number for the positional variable).
I already have accomplished this task using sed and arrays, but since I get the variable using awk, I figured I'd ask this question and maybe I can get a cleaner solution using strictly awk.. I just can't quite grasp it in awk.

template::plugin::yaml
Template::Plugin::YAML(3pm) User Contributed Perl Documentation Template::Plugin::YAML(3pm)NAME
Template::Plugin::YAML - Plugin interface to YAML
SYNOPSIS
[% USE YAML %]
[% YAML.dump(variable) %]
[% YAML.dump_html(variable) %]
[% value = YAML.undump(yaml_string) %]
[% YAML.dumpfile(filename, variable) %]
[% value = YAML.undumpfile(filename) %]
DESCRIPTION
This is a simple Template Toolkit Plugin Interface to the YAML module. A YAML object will be instantiated via the following directive:
[% USE YAML %]
As a standard plugin, you can also specify its name in lower case:
[% USE yaml %]
METHODS
These are the methods supported by the YAML object.
dump( @variables )
Generates a raw text dump of the data structure(s) passed
[% USE Dumper %]
[% yaml.dump(myvar) %]
[% yaml.dump(myvar, yourvar) %]
dump_html( @variables )
Generates a dump of the data structures, as per "dump", but with the characters <, > and & converted to their equivalent HTML entities,
spaces converted to and newlines converted to <br>.
[% USE yaml %]
[% yaml.dump_html(myvar) %]
undump( $string )
Converts a YAML-encoded string into the equivalent data structure. Here's a way to deep-copy a complex structure by completely serializing
the data.
[% USE yaml;
yaml_string = yaml.dump(complex_data_structure);
complex_copy = yaml.undump(yaml_string);
%]
dumpfile( $file, @variables )
Converts the data to YAML encoding, and dumps it to the specified filepath.
[% USE yaml; yaml.dumpfile(".storage", my_data) %]
undumpfile( $file )
Loads the YAML-encoded data from the specified filepath
[% USE yaml; my_data = yaml.undumpfile(".storage") %]
