@ Don...

Each element in the pseudo-array will be a ASCII number from 0 to 255 decimal the value of an 8 bit byte, (so therefore 1 to 3 characters long); a simple audio sample.
(However it could be a 2 byte word from 0 to 65535 decimal, depends how I feel; a more accurate sample if I decide.)
I used newlines as an element separator in one of my examples but any IFS value would probably be OK by me...

You mention ed and I have never, ever used it and I like the idea you put forwards so man page and www it is to see the possibiities.
Is there a limit to POSIX's number of variables, or is that limited to available real memory and element sizes?

@ Jim M...

I code for pure fun and I really love trying the _impossible_ and making languages do stuff they were not designed to do.

@ Scrutinzer...

Not in my local environment at the moment but will try your method out.
