Substantial parts of the standard are now ready. The Abstract Syntax has been in the "proto-standard" as a reference point for over a year. There are also two concrete syntaxes (a "mathematical" version and one in ASCII). The (dynamic) semantics is available as a separate (large) document and was reviewed last month. The only major item still to be finished is the "static semantics" (context conditions) and this is promised for February (I think) next year. So "early next year" there should be a "draft for comment". VDM-SL is now also listed as an ISO work item and I am expecting there to be a meeting in Brussels also early '91.
