That sounds correct to me Ralph.  I’m at least satisfied to know that the current operation is as expected.  I will try the solution suggested by Tim Mooney as well – thanks Tim.

Hi Greg,

 

This behavior is (mostly) documented in the compress record reference manual entry.

 

Is it correct to write what you're missing as:

The compress record in its "N to 1 Xxx" modes, when reading an INP array that has less than NSAM * N elements (or while still filling its internal circular buffer), should use all existing elements of the INP array (or the internal buffer) and calculate as much of the resulting VAL array as possible, before firing VAL monitors and forward links.

 

Such a change should probably have a configuration switch, defaulting to the current behavior.

Sounds like a nice codeathon project!

 

Cheers,
~Ralph
