See your Linkage Editor and Loader User's Guide for allowable xx and yy and linkage editor mode control statements.
The linkage editor uses a program's AMODE attribute to determine whether a program invoked using ATTACH, LINK, XCTL, or LOAD/BASSM is to receive control in 24-bit or 31-bit addressing mode. The loader uses the RMODE attribute to determine whether a program must be loaded into virtual storage below 16-MB, or can reside anywhere in virtual storage (above or below 16-MB).
