Here is the output trace of the clist I showed earlier...
>O> "0"
4 *-* say datatype(x)
>V> "0"
>F> "NUM"
NUM
5 *-* y = 00F0
>L> "00F0"
6 *-* z = c2x(y)
>V> "00F0"
>F> "F0F0C6F0"
7 *-* say z
>V> "F0F0C6F0"
F0F0C6F0
8 *-* say datatype(y)
>V> "00F0"
>F> "CHAR"
CHAR

I didn't think one could add two char strings together..maybe I am
wrong...been around rexx a long long time...

This isn't a bug in rexx.....try this little clist....
/* rexx */
X = 00E0 + 00E8
Say datatype(x) < -- this returns NUM
Y = 00F0
say datatype(y) <--- this returns CHAR
Can't add two character together...

Scott

Reminds me of a problem I thought I had once, how about EXPONENTIAL form
affecting e0 versus e8?
