PJ45315 introduced streamlined E-type loader linkage for frequently entered programs. With PJ45315, you can designate frequently entered programs in the program configuration file (usrconfig.csv). When you subsequently activate loadsets that contain frequently entered programs, the instruction path overhead associated with E-type loader linkage is reduced. However, the special linkage libraries CISO, CTAL, CTIS, CTAD, and CTDF could not be designated as frequently entered programs.
While the special linkage libraries are not frequently present in active loadsets, they are frequently entered. With PJ48028, the special linkage libraries (CISO, CTAL, CTIS, CTAD, ...
