Spectrum ROM: Data at 32D7

Note: the last four subroutines are multi-purpose subroutines and are entered with a parameter that is a copy of the right hand five bits of the original literal. The full set follows:

Offset +3E: series-06, series-08 and series-0C; literals +86, +88 and +8C.
Offset +3F: stk-zero, stk-one, stk-half, stk-pi/2 and stk-ten; literals +A0 to +A4.
Offset +40: st-mem-0, st-mem-1, st-mem-2, st-mem-3, st-mem-4 and st-mem-5; literals +C0 to +C5.
Offset +41: get-mem-0, get-mem-1, get-mem-2, get-mem-3, get-mem-4 and get-mem-5; literals +E0 to +E5.

Used by the routine at CALCULATE. This table is a look-up table of the addresses of the sixty-six operational subroutines of the calculator. The offsets used to index into the table are derived either from the operation codes used in the routine at SCANNING (see S_LOOP, etc.) or from the literals that follow a 'RST $28' instruction.
