Thanks Marc - I'll hold on to that thought if the MSM approach does not work for me.

You're a star - thanks John.

John,  I've had a quick look at your MSM site before I go away.
Can you point me to the MSM-Workstation facility I need to investigate  to produce a Windows executable file.
Appreciate your support John.

Thanks very much for that John.
I'll not be able to try anything for a few days now, but I'll give it a whirl as soon as I get chance.

Thanks for the link Vivek - though it's a bit like Vogon poetry to me at the moment.
Have you a supporting overview that could give me more of a sense of direction ?

Another man of culture & letters I see Jorge !

Thanks for that John.  Yes, I had a vague memory of such from the days when I was a Biomedical Scientist using MSM MUMPS in the UK NHS.
Shame it can't be done now though, I was looking forward to idling away some of my retirement by brushing up my MUMPS !

Thanks Robert - that's very helpful.

Excellent Julius,

I don't understand the reference to mnemonics, but that is just what I needed.

Thanks !

Thanks Robert - that works fine on the first run.
But, I'm getting a <ENDOFFILE> error on subsequent runs. 
I'm sure there's a straight forward answer.  Can you help ?
