Version 02 now supports 20 character medium names. The reason this requires an update is that, after many years, some versions of SMSQ/E (eg SMSQmulator) now do the right thing and take the length count word into consideration, meaning that in most cases you are no longer limited to a 10 character medium name.
Per explains in the readme file with the software that some BASIC commands may still truncate the 20 character names to 10 characters, as they ignore the word length count (e.g. DMEDIUM_NAME$ and STAT), as well as QPAC2 Files menu, although he hopes that these will be updated in due course.
