Further Information
Index Register Contents
Any value stored in the Index register can be referenced in three different
ways:
Using
V
like any other storage register. The value in R
I
can be
manipulated as it is: stored, recalled, exchanged, added to, etc.
Using
V
as a control number. The absolute value of the integer
portion in R
I
is a separate entity from the fractional portion. For indirect
branching, flag control, and display format control with
V
, only this
portion is used. For loop control, the fractional portion is also used, but
separately from the integer portion.
*
Using
%
as a reference to the contents of another storage register.
The
%
key uses the indirect addressing system shown in the tables on
pages 107 and 108. (In turn, the contents of that second register may be
used as a loop control number, in the fashion described above.)
*
This is also true for the value in any storage register used for indirect loop control.
