So, I have imported my 8.0 code into 9.0 but I can��t add an extension method to ScaledDecimal because a repository is missing. I check what to do and get sent to Iceberg. Somehow, as a newbie, I am supposed to understand how iceberg works but, being a 76 year old VAST Smalltalker, I don��t. Surely, when I install 9.0, qashouldn��t I get everything I need for a basic image?
