Today I had a need for an app I wrote 17 years ago in RealStudio, but whose compiled version won’t run under Ventura. All I had to do to get it to compile and run under Xojo 2021 was to comment out a couple of deprecated FolderItem properties and change BinaryInputStream.ReadByte to BInaryInputStream.ReadUint8.
In today’s world of rapid software obsolescence it felt like a minor miracle.
