Ciaran, fantastic! Specifically:

----
DRIVE d,"FILE.DSK",NEW - create new 35TSS DSK image
DRIVE d,"FILE.SDF",NEW+ - create new 40TSS SDF image
DRIVE d,"FILE.SDF",NEW++ - create new 40TDS SDF image
...
The DSK creation of 35 track disks isn't terribly useful for DragonDOS-a-likes. The SDC will auto-expand on writes, but sadly not using the Write Track command used by DSKINIT. To "prime" a DSK image for DSKINIT to succeed, issue something like the following after creating:
SWRITE 1,39,18,"",""
or to expand it to 40TDS:
SWRITE 1,39,36,"",""
----
What is the SWRITE command? Is that a DOSplus thing?
