Transportable program

Each transportable program contains a descriptor and a body. A transportable program descriptor (TP descriptor) indicates the beginning of a transportable program and contains the primary name. The body contains the data that is required to rebuild the program object. The overall structure of a transportable program is shown in Figure 1. The TP descriptor record is mapped by TFMT_TPDESC, which is shown in Table 1.
