Anyone interested in getting a basic understanding of object-oriented concepts should read this information. Using this information, experienced programmers can learn about the REXX language and how it is like and unlike other structured programming languages. Programmers who want to broaden their programming knowledge can learn object-oriented programming with REXX. Users already experienced with REXX can learn about object-oriented programming (OO) in general, and OO programming with REXX in particular.
Programmers who want to make their applications (typically coded in C) scriptable by REXX, extend the REXX language, or control REXX scripts from other applications should consult the application programming interface (API) information in the appendixes presented here. For those who want to control REXX from OS/2 applications, additional information on the OSA Scripting Components API is available in the OSA Guide and Reference.
