Summary and evidence

Learning evidence

• 08_macro_debug.mac driver callable with four arguments.
• 08_build, 08_solve, and 08_extract submacros.
• m08_results.csv for both cases with passes=1.
• .out log and, if applicable, /STATUS output from a diagnosed fault.
• Bug-hunt diagnosis table.
• Reproducibility test between two clean directories.

Exit checklist

• ☐ I validate ARG1…ARG4 before building.
• ☐ I separated construction, solution, and extraction.
• ☐ Each phase fails explicitly when preconditions are missing.
• ☐ I write a CSV with inputs, FE results, references, and passes.
• ☐ I diagnose with /STATUS, .out, and counts.
• ☐ I ran both contract cases.
• ☐ I repeated the test from a clean directory.
• ☐ I did not relax M07 tolerances to force a pass.

Technical traceability

This lesson uses the 2024 R1 Command Reference for *USE, ARG1–ARGn, /INPUT, *CFOPEN, *VWRITE, /STATUS, and /EOF, and the APDL Guide for macro and file organization. The physics and validation tolerances are inherited from M07.
