No. of words 3
Used to allocate memory areas for part programmes.
Principle
The RAM dedicated to part programmes is divided into four areas:
- free access area 0,
- protected areas 1 to 3.
The protected areas are designed to protect certain programmes (resident macros) which may be proprietary and to
ensure integrity of machine operation (the programmes in protected areas cannot be edited).
The total memory size is defined when customising the system and the size of areas 1 to 3 can be modified in words
N0 to N2.
The three protected areas include:
- Customer area 1,
- OEM area 2,
- NUM area 3.
The memory area is expressed in kbytes (1024 bytes).
REMARK: Any remaining area not allocated by this parameter is assigned to area 0 «Free
access user area».
