Of course there's nothing in the Principles of Operation to suggest
that Diagnose is an RX type instruction, and some well known earlier
machines such as the 370/168 and 3033 had very different formats.
Indeed the POO explicitly says Diagnose may be of any format at all;
all you can rely on is the length.

Practically speaking, all machines have used the VM-like format for
many generations, but to be general about Diagnose is impossible.

But this isn't a problem for ordinary instructions, i.e. I know of no
other instructions defined in the POO that have a unique format. In
the event that you find nothing to clone from your existing
instruction set, you will probably have to rely on S-type adcons and
perhaps fancier ORGs.

There's an idea...  Leverage a similar instruction to handle the machine code
conversion hen just fix up the opcode.  Like it.

z/OS does not distribute a DIAG macro, so we wrote our own:

 MACRO ,
&LABEL   DIAG  &R1,&R2,&I1
&LABEL   LA&R1,&I1.(&R2.,0)Diagnose
 ORG   *-4
 DCX'83'
 ORG   *+3
 MEXIT ,
 MEND  ,

Are there, perchance, any samples around to get me started?
