@ 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?

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

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

afgetframesize
AFGETFRAMESIZE(3) AFGETFRAMESIZE(3)
NAME
afGetFrameSize - calculate the frame size in bytes for an audio track
SYNOPSIS
#include <audiofile.h>
float afGetFrameSize (AFfilehandle file, int track, int expand3to4);
PARAMETERS
file is a valid AFfilehandle.
track is an integer which refers to a specific audio track in the file. At present no supported audio file format allows for more than one
audio track within a file, so track should always be AF_DEFAULT_TRACK.
expand3to4 is a boolean-valued integer indicating whether frame size calculation will treat 24-bit data as having a size of 3 bytes or 4
bytes.
DESCRIPTION
afGetFrameSize returns the number of bytes in a frame in a given audio track.
A sample frame consists of one or more samples. For a monaural track, a sample frame will always contain one sample. For a stereophonic
track, a sample frame will always contain two samples, one for the left channel and one for the right channel.
A non-zero value of expand3to4 should be used when calculating the frame size for storage in memory (since 24-bit audio data is presented
in memory as a 4-byte sign-extended integer), while a value of zero should be used for calculating storage on disk where no padding is
added. The parameter expand3to4 is ignored unless the specified audio track contains 24-bit audio data.
