3.8.10 Physical Organisation of %R and %W Variables
Variables
The %R and %W variables are organised in blocks of 128 %R bytes followed by 128 %W bytes then again 128 %R
bytes and so forth until the end of the family.
Reserved Unassigned Variables
Input variables %RE00 to %RE7F and %RF00 to %RF7F are reserved but not assigned.
Output variables %WE20 to %WE7F and %WF00 to %WF7F are reserved but not assigned.
