An Unsigned One-word Record Search Instruction searches the
data (1 word) specified by S2, beginning from the table specified
by S1. When a record matching the specified condition is found, its
record number and data are output to D1 onwards. When an index
register is specified for D2, the address of the matching record is
output to that index register. To not use an index register output,
set #00000000 for D2.

An Unsigned Two-word Record Search Instruction searches the
data (2 words) specified by S2, beginning from the table specified
by S1. When a record matching the specified condition is found, its
record number and data are output to D1 onwards. When an index
register is specified for D2, the address of the matching record is
output to that index register. To not use an index register output,
set #00000000 for D2.

by S1. When a record matching the specified condition is found, its
record number and data are output to D1 onwards. When an index
register is specified for D2, the address of the matching record is
output to that index register. To not use an index register output,
set #00000000 for D2.
