ER-A Model SRV (Service) Mode – File Allocation Overview
Please see the respective Sharp ER-A model Programming Manuals and Dealer Knowledge
Books for the File Group No, name, type, and table numbers.
File Allocation Terminology
The following terminology is used in File Allocation.
• Group No.: (Also known as File Group No.) (See above -File Allocation Overview) This is a
reference number for the file group and is used in the actual File Allocation Programming.
Depending on the model, the Group No. is used and printed on the actual File Allocation Reading.
• File No. / Table No.: (Also known as File Table No.) This is a reference number for the
individual files within a File Group. Depending on the model, the File Table No. is used and printed
on the actual File Allocation Reading.
• File Name: Indicates the purpose of the particular file.
• # Records: This area refers to the amount, or number, of each function that memory can be
allocated for. The actual meaning of each record depends upon the file. ( e.g.: With PLU or
Department Files, each PLU, or Department requires one record; with table files such as PLU Link
or Condiment, each record equals one line of the table.)
“# Records” is usually divided into two columns on the table - DEFAULT (at MASTER RESET) and
MAXIMUM. If the Maximum number of records for the file is denoted by asterisks, it is limited
only by the available memory in the machine.
• # Blocks: The “Blocks” referred to are individual memory areas set aside for transaction data for
each Cashier, Clerk, or Server. Each block of memory has a fixed number of records in it. Each
record corresponds to a particular piece of data that would be printed in a Cashier, Clerk, or
Server Report. Block counts other than “1” are used only
for Cashier, Clerk, and Server Files.
• Label Size: This denotes the number of bytes in the header of the data. In the “ER-A” Series, the
number of bytes in the label MUST be added to the number of bytes in the record length to get an
accurate number of bytes each record requires.
• Record Length (Data Size): Shows the number of bytes required for the data in each record.
• Memory Size: Shows the total number of bytes required for the file at default. In some File
Allocation Tables, the total number of bytes is also shown for the file if it is opened to the
maximum number of records.
