And I guess I'm showing my age: RPG for me means Report Program Generator, and was what we used to program in (alongside COBOL) back in the pre-PC days. (Cf http://en.wikipedia.org/wiki/IBM_RPG_II)

(It was a trip of a programming language-- OpCodes had different meanings, depending on which column they were placed in. Take a look at the sample code in the Wikipedia article.)
