Thanks very much for this. I feel better armed now. Best regards,

This takes care of all the big vs little endian insanity and other file system level things that you don't want to deal with anyway. You will still have to reset all of your indexes using SET.INDEX. Recompiling everything is easy. BASIC BP * (or whatever your basic source file(s) may be). Deciding what and how to to re-catalog things may be a bit more complex. Look at the VOC pointers for cataloged programs and create select lists of globally and locally cataloged programs then create a paragraph to re-catalog everything. Any Unix level commands/scripts/programs will have to be recreated as windows commands/batch files/programs. Try running the SEARCH command on all of your UvBasic program source files and look for "SH -c" to find things executing shell commands. Speaking of which., save this list because you will need to change all instances "SH -c" to "DOS /C". You may want to look into Microsoft Windows Services For Unix which among other things implements a very nice Korn & C shell on your Windows machine. More info here: http://technet.microsoft.com/en-us/library/bb463212.aspx Printers. Universe automatically creates a spooler for each printer set up in windows however the SETPTR command does not like printer names with spaces in them. You will also want to look through your Unibasic source code for the SETPTR command and change printer names accordingly. Again SEARCH is your friend. Check your VOC for file pointers which have pathnames to other directories. These will have to be changed to windows paths. SEARCH (I'm noticing a trend here) for things with an "F" as the first character in attribute 1 and a '/' as the first character on line 2. Those are the biggest things that come to mind right now. You will undoubtedly encounter more.
