Except for the case of registers Ry and R,, it is immaterial as to
which registers you use.
R, is the special object of the Decrement and Skip on Zero ([&]
[DSZ]) operation (presented in Section 4), which uses it as a de-
scending counter (index) in program applications. If this use is
contemplated, R should be avoided for other uses. Otherwise,
it may be freely used.
R, is subject to alteration by the trigonometric functions (includ-
ing the rectangular/polar conversions) and the relational tests
(used in programs). These functions use R, for intermediate cal-
culations (scratch). At other times R, is available for your use.
