I take values from these pdls, check them to see if they are a special value, change the value if needed, and then put them into a perl array.

I would say that is entirely the wrong way to do it.

You need to export the piddle in order to print it. So export it first; then search that for your special values; and only access the piddle elements individually if you find the special value in the exported array -- just to update it with the new value.

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
