Data Facility Product (DFP)
When IBM announced MVS/SP Version 2 (MVS/XA), it also announced Data Facility Product™ (DFP™) as a replacement for and upgrade to the other five products above, which it said would be withdrawn from marketing, effective December 1, 1984. DFP/370 Release 1 (program number 5665-295), announced June 7, 1983, was for MVS/SP Version 1, MVS/SE and OS/VS2 R3.8, and was optional, but MVS/Extended Architecture Data Facility Product (5665-284) was a corequisite for MVS/SP Version 2 (MVS/XA). In addition to enhancing data management facilities, DFP replaced free versions of the linkage editor and utilities.
