Offset 4 points to the next SAVE area, right? And offset 8 to >the previous SAVE area, right? > > So what does offset zero refer to? If you say "R13 goes there", >I won't shoot you. Pointing to itself would provide validity checking, >but is that what offset zero does? If not, then what? > If memory serves, offset zero is used by PL/I for something.
