[Basic & Applied Instruction]
Function and operation explanation
1. 16-bit operation (LOGR/LOGRP)
While the instruction is driven, "m" devices starting from the device specified by are logged until "n"
sectors of extension registers (R) starting from the device specified by and extension file registers (ER)
in a memory cassette are filled.
The number of pieces of logged data is stored to the device specified by .
If a memory cassette is not used, data is not written to extension file registers (ER).

Writing position control area
(Every time one word is used in the data
writing area, bits are set to OFF (0) from
ON (1) in turn from bit 0 of [ +
(1926 n) - 1].
After bit 15 of [ + (1926 n) - 1] is
set to OFF (0), bit 0 of the next device
[ + (1926 n)] is set to OFF (0) in
the next logging.)
