General File Addresses

A TPF general file is a sequentially organized set of data that, in principle, is similar to a TPF general data set. General files, however, are not MVS-compatible and preceded general data sets in the evolution of the TPF system. There are limited classes of general files used by system programs. For example, the general file that is used to load the pool directories is not compatible with general data sets. However, all general files use a sequential data structure and, in principle, correspond to the general data set procedures.

The general file address format that is supported by the FIND and FILE macros is shown in Figure 1 as General File RRN.
