execution condition is ON, READ(190) reads data from the memory area of the
Special I/O Unit allocated word S and transfers it to D through D+N–1. N indi-
cates the number of words to be read. S indicates the rightmost (first) of the two
words allocated for the Special I/O Unit (i.e., the input word).
