The Components of RPG
The RPG language subsystem consists of the following components:
* The RPG symbolic programming language.
The rules of language syntax that you use when entering RPG
programs.
* The RPG compiler.
The RPG compiler translates source statements into a format that
can be executed. In addition, it helps to detect errors at the
source level with extensive diagnostic messages. Programs written
originally to run on other computer systems can be compiled
successfully with few, if any, changes.
* The RPG library.
The RPG library contains run-time procedures for certain
functions, such as input and output operations, output field
editing, and specialized calculations. Run-time procedures are
used by compiler-generated code. RPG's use of the library
procedures is transparent to the user.
