Guru: Dynamic Arrays Come To RPG

Some 12 months ago, when the 7.4 release was announced, I wrote the Guru Tip “7.4 Brings New RPG Goodies” describing the features of 7.4 that were also available on 7.3. I said at the time that I would return later to discuss the 7.4-only features.…

Guru Classic: Overlaid Packed Data In Data Structures

When I re-read this tip while looking for a “Classic” candidate, I was reminded that the underlying issue it addresses, namely how data is actually stored in an RPG program, is one that many RPG programmers don’t really have a firm grip on. That…
