In order to execute load/dump in a TPF environment, the necessary load modules and control modules must be brought into the TPF system files. This is accomplished by creating a tape file (load file) of the required modules in a MVS environment. This load file is then accessed under TPF control and the data is stored on the TPF system files. Once this has been done, the TPF system can honor requests (user or control unit initiated) to load or dump a 3705.
When the contents of a 3705 are dumped, they can be examined by first requesting that a tape file (dump file) be created under TPF control, and then requesting that the dump file be processed in a MVS environment in order to obtain a formatted printout of the dump.
Most functions in this program package reside on the TPF system and operate under its control. The SNA Data Communications function interfaces with this program in order to use the functions it provides. However, several functions of this program operate under control of a MVS system and have some dependencies that must be satisfied. These are described in Programming Systems.
