Changing / shifting multiple dynamic references

The problem I'm working on requires to reassign multiple dynamic references.

I have 20 dynamic references. Let's call them DYN_REF_1, DYN_REF_2..., DYN_REF_20. Additionally, I also have 5 string parameters LOT_NO_1, LOT_NO_2,..., LOT_NO_5.

When the process starts, first 5 dynamic references are assigned to corresponding string parameter, so we have:

'^/DYN_REF_1.$REF':="/LOT_NO_1";

'^/DYN_REF_2.$REF':="/LOT_NO_2";

...

'^/DYN_REF_5.$REF':="/LOT_NO_5";

When certain process conditions are met, I need to shift dynamic references by process parameter PARAM_VAL. Let's assume PARAM_VAL=3 So the result would be:

'^/DYN_REF_4.$REF':="/LOT_NO_1";

'^/DYN_REF_5.$REF':="/LOT_NO_2";

...

'^/DYN_REF_8.$REF':="/LOT_NO_5";

Pseudo code would be like below:

'^/DYN_REF_"+(1+'^/PARAM_VAL.CV')".$REF':="/LOT_NO_1";

'^/DYN_REF_"+(2+'^/PARAM_VAL.CV')".$REF':="/LOT_NO_2";

...

'^/DYN_REF_"+(5+'^/PARAM_VAL.CV')".$REF':="/LOT_NO_5";

(The reason why I modify dynamic reference instead of the string reference is that I need to use them on graphic display. I need to be able to show same string (LOT_NO_X) in different places of a graphic display. I used only 5 string parameters in this example to make this clear, in reality there are many more string parameters, so I can't use other features like hide/show animation effectively. Even if there are better ways to do so, I would like to explore this option first.)

Of course, such syntax is not correct. How can I solve multiple dynamic references dynamically, depending on a variable that determines which dynamic reference I should use?

  As far I am aware you can only manipulate the string in a dynamic reference. If you need to show the value on different places on the graphic you can also dynamically manipulate the position of the value in the graphic. This can be done in Ifix with the position animations if you make the value negative it will basically hide the value.

  I'm not sure I've got my head round what you are trying to do but wouldn't something like this work? The illegal references just don't connect.
  
  '^/DYN_REF_1.$REF' := "LOT_NO_" + (1-'^/PARAM_VAL.CV');
  '^/DYN_REF_2.$REF' := "LOT_NO_" + (2-'^/PARAM_VAL.CV');
  '^/DYN_REF_3.$REF' := "LOT_NO_" + (3-'^/PARAM_VAL.CV');
  etc

  Thank you Pieter for your answer.
  
  Your hint sounds quite good and it works. The only problem is that I use couple of graphics to show these values. First one ends with, let's say, LOT_NO_20 and seconds one starts with LOT_NO_21 etc. Shifting position in this case would be probably still possible but a little bit tricky.
  
  Cedric, to make my problem easier to understand, I would ask a question : If I have 20 dynamic references, DYN_REF_1...20, is there any other way than multiple IF/THEN/ELSE statements to determine first empty Dynamic reference?

  Once this is done, I would have to shift dynamic references by process parameter PARAM_VAL like in my first post.

  Maybe some VBA scripting would help?

  As far as I can see my suggested code does exactly what you outlined eg when PARAM_VAL is 3, DYN_REF_5 will show the contents of LOT_NO_2. I'm obviously missing something.
