table lookup with OR

My existing code checks the value of variable against a table and assigns engine disposition appropriately. i.e. KILL, CONTINUE

I am needing to modify the code to check  2 variables right now.  As long as one of the variable values is found in the table, I want to have a CONTINUE disposition.

Here is the old code…

 ## check value in the Physicians_ALLOW table

             set disp CONTINUE

             set disp [hcitbllookup Physicians_ALLOW $obr16]

             if {![string length $disp]} {set disp KILL}

        echo THE DISPOSITION VALUE===== $disp

Here is what I’m thinking for the new code

 ## check value in the Physicians_ALLOW table

             set disp_obr16 CONTINUE

             set disp_orc12 CONTINUE

             set disp_obr16 [hcitbllookup Physicians_ALLOW $obr16]

             set disp_orc12 [hcitbllookup Physicians_ALLOW $orc12]

             if {![string length $disp_obr16]} {set disp KILL}

             if {![string length $disp_orc12]} {set disp KILL}

        echo THE DISPOSITION VALUE===== $disp

*Would the 2 last if statements eliminate the need for an OR syntax?

**Is there an easier or more efficient way of doing this?
