Lindy, all The open source z390 project has been developed, debugged, and maintained using Eclipse on both Windows and Ubuntu Linux. When I can't figure out what is causing a Java error processing assembler source in the macro assembler, I run the test program using Eclipse and set break-points at the processing methods in question. For large progams it is sometimes necessary to add Java code to test for specific condition and then put the breakpoint in that code to stop exactly where I want. Then you can step through Java code looking at variable values etc to see what went wrong. With the z390 trace options on you can also see the trace info generated for expression parsing etc. on the Eclipse console log which is helpful keeping track of where I am in the macro processor logic vs the lower level Java code. The same applies to the linker and emulator for debugging. I can use Eclipse to set breakpoint on the method for emulating any instruction such as MVC, MVCL, MVCLE, MVCOS and exec z390 load module program with TRACE and/or TEST options on to stop at a specific instruciton and step through the Java code watching the instruction register and memory fetches and the caculations and store operations performed. However, such Eclipse debugging is not for the faint of heart and unless one learns mainframe assembler and Java it could be very confusing dealing with multiple levels of abstraction and emulation. I do have the development of a z390 GUI interactive source level mainframe assembler debugger on my development list (RPI 104 opened 11/18/05) coming after VSAM and SQL support.
