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.
