The record table must be defined in advance with DIM(631).
Valid record numbers range from 0 to NR–1, where NR is the number of
records specified when the table was defined with DIM(631).
When CIO 000000 is ON in the following example, SETR(635) finds the PLC
memory address of the first word of record 3 of table number 10 and stores
this address in Index Register IR11.

SETR(635) writes the PC memory address (m)
of the first word of record R to Index Register D.
