New fields can be added without losing backward compatibility,
because each field is tagged. A version field is included in the
ACC.STA file to identify the supported fields as the system evolves.
» Note: Field 45 in the Job Accounting File example on page 4-21
illustrates that new fields can be added to the series but used where
logical, in this case between fields 6 and 7. Field 45, which provides
information about the interface used, was added in response to a
customer request. The date and time fields appear in the accounting
records for the QMS 2425/2425 TURBO Print System, but they are
unused for this product.

The following conventions are the same for job, paper, and status
files:
„
Tag Identifiers
These three-digit numbers are used to identify fields. The three-
digit number is used instead of a name to minimize use of disk
space. The Dictionary file (ACC.DIC) provides the field names
associated with each tag identifier.
„
String Information
String information for record field values is stored inside braces
(for example, {this is a string}). This allows spaces within strings
and stores only the necessary characters of a string value. String
fields for which no value is specified are stored as {}, instead of
using blanks or the maximum field size.
„
New Records
New records are separated by a <CR> character to increase
readability.
„
Separators
A typical record in any of the accounting files is a sequence of
pairs of tag identifiers and field values separated by commas. The
tag identifier and field value are separated by a colon.
