Mainframe assembler developers as well as other developers may find www.MFATC.org and its discussion group useful as it has a growing collection of coding examples in z390 mainframe assembler, MASM Intel assembler, C++, COBOL, and Java. The first example is a Hello World program in each language along with help information to download and install free software to run each example on Windows 2000 or XP.
