Dear Linda,
I will forward your suggestion to Enterprise Miner product manager to make this available in future versions.
In the meantime, give this trick a try:
Select the SAS Code node that you want to review, then copy it, and then paste it in a text editor like Wordpad or Notepad. You will have some extra lines of XML code that that SAS Enterprise Miner uses and you do not need, but what you want to review will be there for you.
I sometimes do this copy-paste trick as a workaround. I get to "preview" the code in Wordpad or Notepad while the SAS Code node opens.
I hope it helps,
Thanks!
Miguel
