Well DWARF looks interesting, but I'm confused as to your objectives. Perhaps you could clarify. I'd love to. Thanks for the opportunity! The problem statement: "How can I use gdb to examine a COBOL identifier's value and attributes?" As far as I can tell, the recommended answer to this question is to search the generated C code for the C variable name of a COBOL identifier of interest, then use gdb to examine that C variable at the appropriate time. I'll stop here if this answer is correct and is the acceptable status quo. I don't see another answer in the FAQ. I'll stop here if this answer is incorrect. I'll continue if this answer is correct, and is not the acceptable status quo. Based on my earlier research into "how do others solve the unsupported language while using gdb issue?", Mono seems to provide an interesting model (http://www.mono-project.com/Debugging). What they've done is to leverage gdb/Python integration (nice, but too leading edge) to print formatted dumps of Mono data structures. I'd like to propose the same thing for OC. gdb supports syntax like:

The library is copyrighted by Silicon Graphics under the terms of the LPGL. I'll continue this post once I get some confirmation the libdwarf is suitable for inclusion in OCFrom link [1]: ... Many projects generate (gcc for example) and consume (gdb for example) DWARF2/3 information without any reference-to or use-of libdwarf. From link [2]: ...
