Upgrading from 4.3

[Mike Matthews]

Hello Grant,

Ok, so no DAMs, no sessions, No FileOps, just Mac OSX and DF1 with a good helping of Set Read/Write in reversible blocks.  Just like the good old days as I said.  In which case, I don't think you will have any problems at all, just use v6.1, copy the lib & DF1 first.  I think you will be pleasantly surprised.

Unicode only plays a part in the coding of the data in the DF1, so be careful when you convert the DF1 to unicode.  Use the FULL method only, otherwise extended chars such as the French things and other European chars will go funny.  But not a big issue if you follow the right path.

Mike

My application is extremely stable (I have not had a user problem in a couple of years now), and I'd like to keep it like that.  I really am totally unexcited about having to re-invent anything, as I am enjoying my retirement and my other activities.
