Hi Richard,
Result-wise, there would be no difference, unless the flavor you're
using did something bad to system delimiters. The first would upcase the
entire string, and the second would upcase each value separately,
possibly taking a nanosecond or 2 longer. If you expect the data to
ever be multivalued, OCONVS would cover either situation.
Regards,
Charlie Noah

I understand matrix operations well enough to use them frequently, and
in light of this discussion, the following question popped into my
mind:
Is there any difference between:
X = OCONV(X,'MCU')
and:
X = OCONVS(X,'MCU')
Has anyone experienced the results being different?
Thanks!

UPCASE() will also function as OCONVS()
If you put in a dynamic array into UPCASE(), it will upcase the entire string
and
leave the @VM, @AM... untouched.
I use this on UV when reading items, especially for searching, I'll upcase the
entire
dynamic array, then proceed to do my indexes or locates.

Hi Jeff,
The difference is probably only one of performance. Using OCONV
requires the
conversion code to be decoded in order to work out what to do. Using
UPCASE() can go straight off to do the real work without any additional
decoding.
I suspect not, but there may be some difference of interpretation if
you
have NLS installed.

On unidata, can anyone shed light on the differences between
UPCASE(...)
and OCONV(...,'MCU')?
I know OCONVS(...,'MCU') will preserve @VM and other unidata
delimiters,
but for single valued data is their any difference in the above?
