Iterate List

[Earl Coppedge Jr]

I have iterated on fields, groups and segments.  However I am having trouble with iterate on list.

       { { OP ITERATE }

           { BASIS {0 1 2 3} }

           { VAR %L1 }

           { TYPE list }

           { BODY {

               { { OP COPY }

                   { ERR 0 }

                   { IN @null }

                   { OUT {{0(0).EVN.#5.[%L1]}} }

               }

           }}

The object is to null out EVN:5.[0] , EVN:5.[1] ,EVN.[2] and EVN.[3].  But when I run it, only EVN:5.[0] gets nulled out.  What am I doing wrong?

Hmm.  That should work.  Try using lowercase l “%l1” for your variable.

You could also PATHCOPY @null to 0(0).EVN.#5 if you want to null out all components.

Eric,

Try %l1 instead of %L1 (lower case l).

I have never tried Upper case counter identifiers so I can’t say for sure that is the problem – but it is easy enough to try.

Any % variable should work.  But, it is an iteration variable!  You are attempting to use it to access a subfield.

Instead of OUT {{0(0).EVN.#5.[%L1]}} try

OUT {{0(0).EVN.#5(%L1)}}  or

OUT {{0(0).EVN(%L1).#5}}

Depending on what you are tring to do
