Thanks for this. I am now working on alternative ways.

Looks like I am having to flex my not-so-advanced 'C' skills ! Its going
well though.

Thanks

My RedHat 7.0 installation has /usr/bin/expr (and /bin/ash). Changing:
	a=`expr index "$string" ,`
to:
	a=`/usr/bin/expr index "$string" ,`
gives the same result when the first line of the script is:
	#!/bin/ash
as the original line does when the first line of the script is:
	#!/bin/bash

ELKS doesn't seem to have the external "expr" executable but, since it's
part of RedHat's "sh-utils" package, Linux source code should be easy to
find. I have no idea if it needs modification to compile for ELKS.

Unfortunately, "${ ... }" still doesn't work. You might have to find some
other external executable(s) for those lines.
