Hans The Python 3.3 what s new document says that VMS is no longer supported due to lack of a maintainer . So it may be possible to build Python 3.2 on VMS. The current DECnet/Python code wants 3.3, but earlier on I used 3.2 and there isn t much that needs 3.3. (In other words, it would not be all that hard to change it back to allow 3.2.) paul
