Coding in RPG (Report Program Generator) has been taking place since 1959. Of course, the language has changed dramatcially over the last half century.From IBM S/3, to S/34, through the S/38 and S/36 years, and through the AS/400, iSeries machines, and now the Power i products, RPG has been the overwhelming language of choice for application development on the IBM midrange platform.
Control Lanuage programs have been the operational interface between the operating system and application programs from the IBM System/38 to the AS/400, to the iSeries, and the current power systems architecture.
DDS is the language used to define data objects to the IBM Power i operating system. Compiling DDS generates an object definition template that consists of a generic object header, object specfic header and data object.
SQL is a language that may be found on many different platforms. It has become popular on IBM Power plafforms due to two factors; SQL's flexibility, and the RPG's ability to embed SQL within the HLL.
