ER-A Model SRV (Service) Mode – File Allocation Overview
FILE ALLOCATION Overview
SRV Mode File Allocation, also known as memory file allocation and 970 programming, is used to
distribute the memory in a Sharp ECR where the memory is allocable. This allows ‘Files’ to be different
sizes depending on need and for better use of the available memory.
The concept of file allocation is similar to partitioning a hard disk drive. Instead of disk space, you are
working with areas of memory. File allocation allows for dividing and dedicating memory space for the
files to store its data.
Available memory maybe expanded with the addition of an optional memory expansion chip or board.
