Hey Darrel!
    Maybe you can shorten your logic:

Evaluate &A
          When='1'
                    Evaluate &B
                              When='1'
                              When='2'
                              When='3'
                                        Break
                              When-Others
                                        Do Blah
                    End-Evaluate
                    Break
          When-Others
                    Do Blah
End-Evaluate


   But if you seriously want to clarify your logic:
LET $Lets-Do-It = "NO"

IF &A = 1
            IF &B <>1 AND &B <> 2 AND &B <> 3
                        LET $Lets-Do-It = "YES"
            END-IF
ELSE                                                                     
   !  IF &A IS NOT 1
            LET $Lets-Do-It = "YES"
END-IF

IF $Lets-Do-It = " YES"
            DO The-Next-Step
END-IF         

                      Happy computing,
