Need help learning IBM mainframe assembly language? VisibleZ can help you visualize exactly what the
mainframe is doing as an assembler program executes. Besides the software, this site provides many hours of lessons that will build your assembler skills. These lessons are specifically designed to accompany VisibleZ.
Download VisibleZ here. You will get a zipfile that contains an executable Jar file that contains the source code. Double click the jar file to run the program. If you want to look at the Java code inside the jar, the file that runs the program is called Runner (This is not required). You will also get a Codes folder that contains all the object code snippets that run in VisibleZ and demonstrate many instructions.
