The Finalist LPCF transaction does not have input/output (I/O) capabilities other than the use of the Finalist master files. System exit points help update a file's addresses. These exit points can call I/O routines. One exit point is called to read an address into the Address Lookup Screen (input exit). The other is used to write addresses from the Address Lookup Screen (output exit).
Use these exits to read an input file (PF7) and ensure that an address is correct. After validating and/or correcting an address, the output exit (PF8) can write the corrected address to a new file or the file used as input. This is a highly effective way of ensuring address files are correct and contain deliverable addresses.
You can call the input exit using the PF7 key from the address lookup display. You can call the output exit using the PF8 key.
