Hi everyone. I have been using Pharo sine I got my M1 MacBookAir in late December. Before then, I was a VAST user since around 1995. I have a question about packaging. Example, in VAST, I have an Application called Family_Accounts. Inside that I have some classes such as FAEntry, FABudget and so on. If I wanted to extend String to add an instance to convert to ScaledDecimal but using my special amount strings. I select the New menu item and then select either a class or an extension. As I want to extend String, I select Extension and then, within my Family_Accounts, I can see the String class so that I can extend it. In Pharo, I can have a package called Family_Accounts. I can extend String, OK but my extension stays within the original package with, optionally, a Family_Accounts classification. I canât see how to add String to the Family_Accounts package to keep everything together in one place. Can this be done? David
