ER-A440, 450T, 520 & 530 File Allocation Overview

File allocation programming for the ER-A440, 450T, 520 and 530 uses File Groups to reserve areas of

memory for data storage.

During file allocation, file groups work much like a batch file or command file does in an operating system

or software program. A single File Group may reserve areas of memory for a single file table or

multiple dependent or related file tables.

Programming by “Group” allows certain portions of some files (such as text length for Departments and

PLUs) to be changed without affecting other programmed areas of the function.

Depending on the File Group Type, the file allocation requirements will vary.
