Thanks David the references were very useful as well as chapter 13 of
your book, I am trying now to "modalise" my widgets. I encountered
another issue that of EXECUTE command. RSI's Interfile reader
(READ_INTERFILE) uses it and I had to find a way around it so as to
work in VM environment. This issue worries me though that more
routines from RSI might use EXECUTE...
Thanks again,
Antonis

I'm afraid you are going to have to learn how to write a proper
modal widget. You can't rely on blocking in the VM. Sorry. :-)
