Dan,
A belated reaction, sorry about the delay.
I just checked the source code. It seems START is treated as a synonym
of CSECT.
At the java level the z390 code does not seem to expect an argument.
If you need it, we could raise an RPI.
Kind regards,
Abe Kornelis.

We used to write a LOT of CMS Transient Area modules, and always put START
X'E000' at the top. TBH, that was 40 years ago and I didn't exactly know why at
the time, then stopped thinking about it! Now I know.

Yes, that's what START did.
I wrote a single-pass S/360 assembler for teaching purposes.
One of the purposes was to assemble to location 0,
using absolute addressing. (Yes, I know that the low assresses on the real
machine were not available fot that purpose, but with START 0
& base register 0,
