Application and System Support

Many of the areas addressed in this section of this document could be classified, in some respects, as application support. However, there are several areas that are designed specifically as interfaces between the hardware and system programs, and between the application programs and system programs, which will influence the way application programs are designed.

Many of these areas, which are often referred to as packages, must either be included or excluded from the generation of the TPF system via the use of keyword parameters that are associated with various SIP macros. Several require that specific fixed file records be allocated for their use. In some cases, there are requirements to initialize records which are then loaded to the system via pilot tapes (see Communication Pilot Record Generation). There are even cases where the user may be required to physically update the source code of system programs to achieve specific results, and other cases where defined user exits have been provided.

In summary, the overall purpose of this section of the document is to introduce these various packages, to explain their basic purpose, and to explain the generation requirements for them.
