RPG steals a trick from its older brother COBOL to make moving data just a little bit easier.
Written by Joe Pluta
Practical programming is often about the little things. For example, one of the issues in programming multi-tiered applications is moving data between tiers. In message-based programming, you can and should reduce the number of traveling fields by using a data structure that contains only the fields you need. The problem is that you have to populate those fields with individual MOVE instructions and, with large tables, identifying every field can be tedious and error-prone (especially when the fields have short names). EVAL-CORR gets around that problem.
You don't need to write a program to run common SQL statements.
