12. 1/2002JNM 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

13. 1/2002JNM 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
