Re: EPICS7 roller-coaster

Hi Michael,


Here is a little feedback, actually something to add to a wish list.


pvget and pvmonitor really need a way to limit the output, similar to the -# <count> flag in caget and camonitor.  Since pvget could be returning multiple array fields the simplest implementation would be to use this limit for the number of values to print on each of them.

I often want to do pvget or pvmonitor on an NTNDArray structure.  But I don't want to see all 2+ million values of the image, I just want to see a few values and the rest of the structure.


Thanks,

Mark

I'll address this piece first, and leave the rest until my desire to
counter-rant has faded.  I'm not unhappy with you (Rolf), but rather
with the "community", and  the difficultly of getting the (to me) all
important user feedback during the development cycle of a module,
as opposed to 3 years later after multiple releases.

This issue has been fixed, but not released.

pvput test:rect height.value=33
