Processing Related to Index Registers

The CJ-series CPU Unit's Table Data Processing Instructions complement the functions of the Index
Registers. Table Data Processing Instructions can be broadly divided into stack processing instructions
and table processing instructions.

Purpose
Operate FIFO (first-in SSET(630), PUSH(632), FIFO(633),
first-out) or LIFO (last-in LIFO(634), SREAD(639),
first-out) data tables, and SWRIT(640), SINS(641),
read, write, insert, delete, SDEL(642), SNUM(638)
or count data entries in
data tables.
Find integer or floating- MIN(183), MAX(182), MINL(175),
point decimal values MAXL(174), MINF(177),
such as for the maximum MAXDF(176), MIND(179),
value, minimum value, or MAXD(178), SRCH(181),
checksum. SUM(184), and FCS(180)
Perform various other Combine Index Registers with
table processing such as instructions such as SRCH(181),
comparisons or sorting. MAX(182), MIN(183), and compari-
son instructions.
Search and sort records RSRCH <(360), RSRCH <=(361),
in a specified area (num- RSRCH =,(362), RSRCH >=(363),
ber of words and range) RSRCH >(364), RSRCH2 <(370),
registered by the user. RSRCH2 <=(371), RSRCH2 =(372),
RSRCH2 >=(373), RSRCH2 >(374),

RSRCH4 =(382), RSRCH4 >=(383),
