Open Source Rexx Formats and Protocols

This is a modified version of the CRC algorithms by Lammert Bies. It supports more algorithms and has been ported to several languages. It's also useful for learning how to do hexadecimal calculations and bitwise operations in various programming languages. Disclaimer: These test programs demonstrate the calculation of CRC. I made these translation with a basic knowledge of each language. They may or may not be appropriately formatted / secured / robustified / idiot proofed or any similar programming issues.

An XML parser written in the REXX programming language. It runs on mainframes (z/OS Rexx) as well as Windows and Linux (Regina or ooRexx). Includes example Rexx programs that use the parser such as: JCL2XML (converts z/OS JCL into an XML format), AUX2SVG (converts a z/OS CICS auxiliary trace file into a visual SVG format), PRETTY (an XML pretty printer), DEVISIO (an example of removing unwanted tags from an SVG file).

This will read a USB Human Interface Device (HID) report descriptor from the specified input file then attempt to decode it and, optionally, create a C language header file from it. It also does some minimal sanity checks to verify that the report descriptor is valid. The input file can be a binary file or a text file (for example, an existing C header file). If it is a text file, it will concatenate all the printable-hex-like text that it finds on each line (until the first non-hex sequence is found) into a single string of hex digits, and then attempt to decode that string. You can feed it an existing C header file and it will decode it as long as you have all the hex strings (e.g. 0x0F, 0x0Fb2) at the beginning of each line. Commas (,) and semicolons (;) are ignored. Oh, and it's just a Rexx script - not an executable.
