In a previous post I wrote about the different types of numbers that could be used in RPG. Alas, we have been spoiled with RPG as there are less types to choose from in when defining numbers fields in DDS files and columns (SQL) DDL tables.
DDS files
DDS files come in different forms, and they all have their own rules as to the types of numbers are valid. I am only going cover the major types, which in my opinion are:
- Physical files
- Display files
- Printer files
