SX/B address testing

Hi all;
I'm trying to see if SX/B will be suitable for some of my needs, and I'm trying to do some assembler vs SX/B comparisons.
So I'm just learning SX/B.
In SX/B one can do an IF-Condition-Then statement where the condition is the comparison between two 16 bit words. All is fine. However when I want to compare a 16 bit word to a defined label, I get a BYTE PARAMETER EXPECTED message, and quoting the label.
Example...······I cannot get this·to work
····· Pointer var word
····· IF Pointer > Table THEN Exit
Exit:
Table:
······ DATA ......
Am I doing something wrong?
I can of course work around this by first·assigning the address to a temporary·16 bit variable, and then using that in·the comparison, but this means extra code which I expect should not be neccessary.
Example...······this does work
····· Pointer var word
····· Temp var word
····· Temp = Table
····· IF Pointer >·Temp THEN Exit
Exit:
Table:
······ DATA ......
Cheers,
