Experimental Physics and
Industrial Control System

I have observed the following undesirable behavior in a combination of longout record and a EDM Text Control widget set to display format "Hex":
When I enter the value 0x80000000 in the text control, it gets converted in the record to 0x7fffffff.  I suppose that either the EDM widget or the epics longout record perform signed conversion.  But why 0x7fffffff?  I have tested this on a pure software IOC running on Linux.  Now, when I enter 0x80000000 I want that to be the value in the record.  Is it possible that longout is not appropriate for this?  If so, what record type should I use?
Thanks in advance,
Zen
