The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
We find this to be exactly the behavior we want for keeping track of
time-dependent matters. It's more accurate (precise?), in my view, than
executing a TIME opcode or gettimeofday() function, then converting to the
right date format, then writing the record. Of course, we don't update it
with "last used", purely for ordering various events by time.
So this is a matter of knowing how the system behaves, using this knowledge
to whatever advantage you see in it.
I suspect that this behavior (default values for unspecified fields in
logicals) has been around for a long time. It's use was news to me, and for
us it is effective.
Now my question is, will an update through the logical file update the
timestamp as well? I doubt it.

This explanation makes sense; unfortunately, the documentation doesn't.
You don't want the system "helping" you by automatically posting values to
fields you want to keep "empty" (like timestamp indicating a "last use").
A before trigger is an excellent suggestion but my requirement is simple;
adding another line of code to the program is the best solution (it provides
the desired result with minimal code and no confusion).
Doug, thanks...
