So why not a "test bit" instruction, instead of needing to generate a "bit mask" from the 
"bit number", then do something like an EX of an NI or some such (as I'm sure many have seen and 
done). This could be a simple RX format instruction. The register would contain the bit number, from 0 to 7 
(specification exception if not in range),
Seemed you don't like these SI/RI format TM, TMHH, TMLL, TMHL, TMLH and TMY 
instructions? They're doing these tests but with 'bit mask'.

  SLR   R0,R0
  L     R1,STORE_NUM
  D     R0,=F'8'
  TBIT  R0,STORE_BIT_STRING(R1)
TBIT? Perhaps someone can write a macro doing that?
