2.2.2.6 Formula Elements

  • Article

Some Ptg records (section 2.5.198.25) require extra data that is not stored in the Rgce (section 2.5.198.104). When an Rgcecontains one or more of these Ptg records, the containing formula structure includes an RgbExtra (section 2.5.198.103) containing the data for those Ptg records. The size of these components is specified by the RgbExtra structures. The Ptg records do not contain an offset into the RgbExtra for their data. The Ptg records that require a corresponding structure in RgbExtra are specified in section 2.5.198.103.
