  1. syntax problem?

    hi all

    i have the following script which is not working like it should.
    the second IF statement seems to be true always even if Rl is equal 0:


    << "Voltage Divider" {
    { "Ue:" "Value of Ue in Volt" 0 }
    { "R1:" "Value of R1 in Ohm" 0 }
    { "R2:" "Value of R2 in Ohm" 0 }
    { "Rl:" "Value of Rl in Ohm" 0 }
    }
    { }
    { 0 0 0 0 }
    { 0 0 0 0 }
    INFORM
    IF THEN OBJ-> -> Ue R1 R2 Rl
    << IF 'Rl>0' THEN
    'Ue * ( ( (R2 * Rl) / (R2 + Rl) ) / ( R1 + ( (R2 * Rl) / (R2 + Rl) )
    )' ->NUM "Voltage of Ua is" ->TAG ->STR MSGBOX
    ELSE 'Ue * ( R2 / (R1 + R2) )' ->NUM Voltage of Ua is" ->TAG ->STR MSGBOX
    END
    >>

    ELSE END
    >>


    maybe a stupid newbie mistake. any ideas?

    thanks a lot
    p.

    Clue :
    at this point you get more than just Ue, R1, R2 and Rl on the
    stack

    > -> Ue R1 R2 Rl


    but here you seam to assume only Ue, R1, R2 and Rl

    Try following the OBJ-> command with a DROP

    or replacing the OBJ-> with EVAL.

    i got it to work - i didn't realize that cannot simply ignore the
    element count in the stack...

    Thanks to all for the quick assistance!
