Dear Steven,

Thank you for the answer.

I see that if we want to have something like this functioning, we need

to use several records with appropriate "connections" between them to

get things done..

I was thinking about a second waveform that would act as "subArray". To

bad that we can not set maximum number of elements for waveform (similar

as for subArray) and be allowed to process only desired range.

Best regards,
Hinko

I did something similar a number of years ago to allow tuning of ramping waveforms. I used a subArray with a length of one element and an adjustable index into the array to inspect the elements, and an aoRecord to adjust that element for tuning. The aoRecord wrote to a genSub record which recalculated the waveform (recomputing the rest of the waveform based on the new input and smoothing around the changed element to avoid discontinuities). The genSub then populated the waveform output record which controlled the hardware. As I recall, I needed to do some tricks with DISV to control record processing (run mode versus tuning mode) and to sync the aoRecord with the waveform element when not in run mode.
