Hi MadeInGermany...

I didn't try the Perl builtin 'printf' as 'print' DID support terminal colours, so I made an assumption that 'printf' wouldn't plot either.

I will experiment with plotting using 'printf' and get back to you.
If I get stuck and plotting is still unable to be done then I will come back on here for solutions.

TIA.

EDIT:
Well a cold start with the builtin 'print' DOES work but believe me, I tried for hours with hard coded valus as well is variables and I kept getting an major 'scalar' error report finally ending up saying it couldn't complie the code - hence reverting to the 'system' command.

I honestly do not know why I kept getting major errors when now it is working..

Here is the original test code i couldn't get working, but it is actually calling me a liar now.
Code:
#!/usr/bin/perl
# plotter.pl

use warnings;
use strict;

# Centre of terminal window.
my $horiz=34;
my $vert=11;
my $plotter="\033["."$vert".";"."$horiz"."fHello World.\n";
print "$plotter";

And finally I am in the process of using 4 capture modes, DEMO, DSP, ALSA and QT, (DEMO is obviously working using the builtin random number generator but the final cut will create a raw 'noise' file using /dev/urandom).
I have already done the section to create the AppleScript and call it, but not done the binary file to byte sized decmial array or list yet but I am working on it...

SYNOPSIS

       /usr/ucb/plot [-Tterminal]

DESCRIPTION

       The plot utility reads plotting instructions (see plot(4B)) from the standard input and produces plotting instructions suitable for a  par-

       If no terminal is specified, the environment variable TERM is used.  The default terminal is tek.

ENVIRONMENT VARIABLES

       Except for ver, the following terminal-types can be used with `lpr -g' (see lpr(1B)) to produce plotted output:
