Thanks Jon.
That looks to be what I am looking for.
I'll put this into a test version of the program and give it a shot

I have a demo program based on an example that Carsten Flensburg posted
here
some time back which uses the DSM APIs. I have included it below since I
can't find the original in the archives. It is intended for debugging
purposes. I have used it as part of a PSSR (and similar) error diagnostics
processes.
There is also a more comprehensive set of code (albeit for a different
purpose) here that you could adapt to your needs. Mine simply grabs the
buffer - this one replaces the screen attribute characters so the whole
thing is readable - you'll certainly want to do something like that. Wrap
the calls up as subprocedures, plug them into appropriate spots and off you
go.
