  1. Edit, Assemble, Link & Debug JNM

  2. Files Created JNM

  3. Files Created (Verbose) • Source File (.asm) – an ASCII file • Object File (.obj) – a machine-translation of the program • Listing File (.lst) – a copy of the program’s source code, suitable for printing, with line numbers, offset addresses, translated machine code, and a symbol table. JNM

  4. Files Created (Verbose – cont) • Program Database File (.pdf) – updated during the link step if –Zi option is used with ML. JNM

  5. Files Created (Verbose –cont) • Map File (.map) – a text file containing information about the segments contacined in a program being linked. - EXE module name • timestamp from the program file header • List of segment groups in the program – with each group’s start address, length, group name, and class. • List of public symbols, with each address, symbol name, flat address and module where defined. • Address of the program’s entry point. JNM

  6. Editors • EDIT – available with DOS • Notepad – Text editor • PWB Editor– Programmer’s Workbench • MASM’s management tools for assembly code • PFE – Used in lab • Ultraedit, etc… - available free on internet JNM

  7. Assemblers • MASM – Microsoft Assembler • TASM – Borland’s Turbo Assembler JNM

  8. Debuggers • Debug • Debug32 – Included with Uffenbeck book • Codeview – symbolic debugger (source code can be viewed while debugging) JNM

  9. Codeview Screen JNM

  10. Codeview Windows • Source Window • Use options button to toggle between options • Memory Window • Can change size to increase amount of memory seen • Register Window • Command Window • Output Window(F4) – full screen • Debugging – • F8 – trace – T - (with procedures) • F10 – step - P - (without procedures) • Breakpoints(Data – Set Breakpoint – Break at Location) JNM

  11. Source Code Template Source Code Template JNM

  12. How Do you Assemble your Code • Assuming you have created a source file using an editor, you must now assemble it. • You could type in • MASM /z/zi filename • LINK /co filename • MASM contains ML executable program • ML /Zi /Zm /Fm /Fl filename.asm /link /co c:\irvine\irvine JNM

  13. Better Ways to Assemble and Link Files • Run make16.bat (or make32.bat) • Run make16 from the directory where your source file is located • Set path to find masm615 • C:>path = c:\masm615 • C:>make16 filename • C:> cv filename JNM
