Choosing Addressable Registers
|
|
Except for the case of registers R8 and RR9, it is immaterial as to which registers you use.
|
|
|
|
|
R8 is the special object of the Decrement and Skip on Zero (gDSZ) operation
(presented in Section 4), which uses it as a descending counter (index) in program applications.
If this use is contemplated, R8 should be avoided for other uses. Otherwise, it may be freely used.
|
|
|
R9 is subject to alteration by the trigonometric functions (including the rectangular / polar conversions)
and the relational tests (used In programs). These functions use R9 for intermediate calculations
(scratch). At other times R9 is available for your use.
