Rapid Development System (RDS)

One of two implementations of the 4GL application development language for UNIX systems. The RDS compiler produces p-code that can then be executed by a runner. The other implementation of 4GL for UNIX systems is the C Compiler Version; it uses preprocessors to generate C code, which is then compiled and linked to make a standalone, executable file. 4GL for Windows includes both the p-code compiler/runner and the C code compiler.
