Hi David!
Thanks for your prompt response. When the UPDATE seemed to not be working for this particular table (TABLEUPDATE(.T.,.T.) returned .F.), I swithced it over to Manual Update so I could isolate the command. The original inoperable command looked somthing like this test cursor (ORDER is NUMERIC):

update test set
ORDER = ?crsTest.ORDER,
DETAIL = ?RTRIM(crsTest.DETAIL),
INSTOCK = ?crsTest.INSTOCK,
DETAIL2 = ?RTRIM(crsTest.DETAIL2)
where PK = ?crsTest.PK

...these two work:

update test set
DETAIL = ?RTRIM(crsTest.DETAIL),
INSTOCK = ?crsTest.INSTOCK,
DETAIL2 = ?RTRIM(crsTest.DETAIL2)
where PK = ?crsTest.PK

...and...

update test set
[ORDER] = 1,
DETAIL = ?RTRIM(crsTest.DETAIL),
INSTOCK = ?crsTest.INSTOCK,
DETAIL2 = ?RTRIM(crsTest.DETAIL2)
where PK = ?crsTest.PK

In resigned despeiration, I tried:

update test set
[ORDER] = ?crsTest.[ORDER],
DETAIL = ?RTRIM(crsTest.DETAIL),
INSTOCK = ?crsTest.INSTOCK,
DETAIL2 = ?RTRIM(crsTest.DETAIL2)
where PK = ?crsTest.PK

...to no avail.

I have not used the profiler yet...I mean seriously, I haven't had the chance to use it, ever. I will learn it now!

If you can give me a solution to this, I'll eat a red-herring raw, and you can insult my intelligence all you like!
