  3. *   MERGEC                                                         *
  4. *       This program reads in a Turbo C file and the Assembler        *
  5. *       file that tcc produced (with the -S switch) and combines   *
  6. *    them into a single file.  This function is useful when     *
  7. *    trying to debug in Assembler code with a hardware debugger *
  8. *    or if you are just interested in how well Borland        *
  9. *    generate Assembler code.                   *
  10. *                                                                  *
  11. *   COMMAND FORMAT:                                                *
  12. *     MERGEC asmsrc csrc mergefile                   *
  13. *             or                           *
  14. *    MERGEC filename                           *
  15. *         and the program will assume the following:           *
  16. *                assembler source --> filename.asm       *
  17. *                C source  ---------> filename.c           *
  18. *                "merged source" ---> filename.mer       *

  20. *                                   *
  21. *   This program was adapted from source by Dan Mick in the        *
  22. *   July 1989 issue of "Microsoft Systems Journal."   The          *
  23. *   original program supported the Microsoft compiler and MASM.    *
