This is how to download reports from a mainframe repository to a PC.This discussion is confined to the older method of accessing mainframe based reports from the PC with CA Unicenter Document Viewer 2.1 and Attachmate Extra.
An emulator is required (Attachmate Extra! for the purpose of this document) and DVPC must be able to interface with that emulator. HLLAPI (High Level Language Application Programming Interface) is the link between Extra! and DVPC. That is what this document is all about – how to configure these component applications so they can appropriately communicate with one another and transmit reports.
