Sorry, must have missed your post.

I'm personally not bothered about Graph, as I don't use it anyway.

I presume you know that OS/2 is even deader than DOS. Even IBM pretend that it
never existed.

Yes. Last time I looked (which was quite a while ago), VP was an "OK"
compiler - the generated code is nothing special, but it's not horrendous
either. Of course, generating code for a 32-bit flat model is inherently
easier than the TP segmented Large model.
