    I would like to start iterating starting with index one of a repeating field.

    where/how should I init the $f1 variable field ?

      Robert,

      You cannot cause the ITERATION Action to begin at any specific point. However, for your case, inside the ITERATE you can modify the %f1 counter. I would rather modify my own counter (say %f2) and use that in the address path of the following Actions. That way you would always be able to tell where the ITERATION was as %f1 would have the real value of the iteration count.

      You can reference and/or modify iteration counters by prefixing the counter with a $.

      Such as a MATH ADD Action where you are trying to add 1 to %f2:

      The Source column would have =1 and $%f2.

      The Destination column would have $%f2.

      You would then use %f2 anywhere appropriate in the Source and/or destination address paths.

      If you want to skip given iterations you could take the lines currently inside the iteration and surround them with an IF statement that is only true for those iterations you want to occur.

      ITERATE

         copy …

         copy …

      ETC

      Would become

      ITERATE

         IF %f1 > 0

             copy …

             copy …

      ETC

      Chris,

      A small but not insignificant change to your IF Action:

      IF $%f1   <---- Note the $   🙂

      So there you have a couple of ways to resolve your issue one where you just use your own counter and start it with one more than the iteration counter, and one where you utilize an IF Action to detect where in the iteration set you are.

      Cloverleaf(R) seems to always provide more than one way to get the job done.

      Just wondering if you were paying attention.  😉
