Find about indexing.No alert I found.

In a project in the decade of 1990, the use indirect addressing caused:

*Registers not in use, in instants he presented trash.
*Registers-Distant positions: were add trash.

The registers not special, not allocate any instrution in manual.

Question 01 : The old programmers, if see problems of hardware in use of this instruction.

The parts program erased, identified group the operations matemathics it is cause.

My etics, quiet in the name of the PLC, only it manufactured Asian.

(The program was send the manufacturer, but this him silenced.
I think, problem go project struture registers internal of microcontroler)

Question 02: Colleagues, which interesting application of this instruction.

I like of indexing, use with caution.
