NetRexx - Programming language derived from Java and Rexx Version.0.50 NetRexx is a new programming language derived from both Rexx and Java(tm); the rules of suntax closely follow those of Rexx, while the semantics often follow Java. It is intended as a dialect of Rexx that can be as efficient and portable as Java, while preserving the low threshold to learning of the original Rexx language. Further, the language is intended to be even more keyword safe than Rexx: it should be possible to re-compile or execute an exising NetRexx program _from source_ at any time without additions to the keywords known to the language invalidating an existing program. Like Rexx, NetRexx is designed to allow clear separation of its concepts, so it may be introduced gradually. Also like Rexx, sesible defaults are defined to aid ease of use -- especially for the novice programmer. These defaults can be turned off for the programmer who needs stricter type-checking and certain other features. The Java virtual machine environment is assumed to be a platform for NetRexx, and this places some constraints on the NetRexx language. For example, the semantics of type resolution are in part determined by the environment, not the language. The constraints of efficiency, safety and environment implied that this language would have to differ in some details of syntax and semantics from Rexx; it could not be a fully upwards-compatible extension of Rexx. The need for change, however, has offered the opportunity to make some simplifications and enhancements to the language to strengthen the original Rexx design, and incorporate other additions from ANSI Rexx and Object Rexx. NOTE: This program requires HPFS, Java and Rexx to be installed. You will need to unzip this file with a program that supports long file names.
