Table Data Processing Instructions Section 3-17
The following diagram shows the basic structure of a record table. Each
record in a table has the same number of words.
Index Registers (IR) can be used to indirectly reference table data. Address
calculation of the record can be easily made by using the SETR(635) (SET
RECORD NUMBER) instruction and GETR(636) (GET RECORD NUMBER).
Range Instructions The range instructions included here act on a specified range of words to find
the maximum value (MAX(182)) or minimum value (MIN(183)), search for a
particular value (SRCH(181)), calculate the sum (SUM(184)) or FCS
(FCS(180)), or swap the contents of the leftmost and rightmost bytes in the
words (SWAP(637)).
