Standard Data/Message File

As part of the released system, there is a file included known as the standard data/message file (SDMF). This file is associated with the offline running of the system test compiler (STC) and consists of two parts, both of which will need to be expanded by the user.

The first part is known as the data record information library (DRIL) and is used to symbolically define all data records to be created using STC. The released version of this file contains the symbolic definition of all system-related data records. Users should add to DRIL the definition of their own application data records.

The second file is known as SDMF and is similar to DRIL but in addition it allows the records to be initialized with information contained within the SDMF file. Individual fields within the data record can be initialized uniquely. In addition to defining his records in DRIL the user may wish to add his new records to SDMF. For example, as a minimum the user may initialize the record headers (e.g., the record ID) using this facility.

More information about both SDMF and DRIL can be found in the TPF Program Development Support Reference. All of the system-related data records, which have been previously mentioned in this document, are defined in DRIL and many are also initialized via SDMF.
