F93 16-bit data
digit combine
UNIT S, n, D The least significant digit of each of the “n” words of
data beginning at “S” are stored (united) in order in “D”.
7
F94 16-bit data
digit distribute
DIST S, n, D Each of the digits of the data of “S” are stored in
(distributed to) the least significant digits of the areas
beginning at “D”.

F96 16-bit table
data search
SRC S1, S2, S3 The data of “S1” is searched for in the areas in the
range “S2” to “S3” and the result is stored in DT90037
and DT90038.

data search
DSRC S1, S2, S3 The data of (S1+1, S1) is searched for in the 32-bit
data designated by “S3”, beginning from “S2”, and the
result is stored in DT90037 and DT90038.
