UCS2 is perhaps more commonly known as "Unicode".
It's the 2 byte per character subset.

As far as I know, these were never officially in
plan for this release.

On V4R2, I would probably use %EDITC since it is
less dependant on the size of the numeric variable.

Oh yeah, I forgot about another enhancement.  In
our next release, %CHAR will now allow numeric
operands.  The result will be a varying length
string with leading sign if negative.  %CHAR(num)
is roughly equivalent to %TRIM(%EDITC(num:'P')).

One more thing now that my memory is back:  Hex
literals can now be used in places where a numeric
literal is expected.  If the hex literal represents
8 or fewer bytes, the value can be considered as an
unsigned numeric value.  That is, X'FD' in a
numeric context has the value 253 (not -3).

Cheers!  Hans
