Hi,

I have updated to KDB 3.5 and it seems (:) (next/return) does not work under debugging mode. I would expect it to continue in execution return empty if nothing is provided but seems to stuck. It worked before. Any suggestions?

Thank you.

Best regards,

Jakub M.H.

Hi Pierre I downloaded &nbsp;latest version KDB+ 3.5 2017.06.15 Copyright (C) 1993-2017 Kx Systems .

The problem persists in spite of brackets that it gives me when entering return (:) command. But it does not continue as expected.

this looks like q.k version mismatch. could you check if your q.k is from the same .zip as the binary?
