The following is an example of a linker invocation to link and locate the modules and to deter-
mine the proper windowing.
RL196 MOD1.OBJ, MOD2.OBJ registers(100h-01ffh) windowsize(32)
The above linker controls tell the linker to use registers 0100–01FFH for windowing and to use
a window size of 32 bytes. (These two controls enable windowing.)
The following is the map listing for the resultant output module (MOD1 by default):
