A physical file can contain only one record format. Specify the record format in either of two ways:
Specify the entries in the following order to define a physical file:
You can find an explanation of file-, record-, field-, and key field-level specifications in Introduction to DDS Reference.
You can find the syntax rules for specifying DDS keywords in DDS Syntax Rules.
The maximum number of fields in a record format is 8000. If any of the fields in the record format are date, time, timestamp, variable length, or allows the null value, then the actual maximum number of fields can be less than 8000. The maximum number of fields can vary depending on the number of fields and combinations of fields that occur within the record format. The maximum number of bytes in a record format is 32 766 if variable length fields are not included and 32 740 if variable length fields are included.
