Example 3:
Example of coding a record in the internal memory – e.g. record
No. 13 on the page 559
The record no. 13 (rec 13) on the page 559 is read out from the registers
4553 – 4556 (unsigned short registers – 2 bytes, 1 record includes 4 unsigned
short registers) after entering the value 559 into the register 4500. The initial
register containing the beginning of the record is found on the relationship:
R
0
4501 + rec 4
4553.
