🚀 How to Use

1. Set up MASM and DOSBox:
   Follow this video tutorial to download and set up MASM in DOSBox:
   👉 How to Download MASM and Mount it in DOSBox

2. Place .asm Files:

   • 🔴 Ensure all .asm files are placed in the same folder where you mounted MASM in DOSBox (e.g., C:\Dbox).
   • This step is necessary for MASM and DOSBox to locate and assemble your files without errors.

3. Common MASM Commands:
   Use the following commands to assemble, link, and execute your programs in MASM:

   mount c c:\< FolderPath >  # Mount the folder with MASM and .asm files
   c:                       # Switch to the mounted directory
   masm filename.asm        # Assemble the .asm file
   link filename.obj        # Link the object file
   debug filename.exe       # Debug the executable

   Inside the debugger:

   • u : View code
   • g : Execute the program
   • d 076A:0 : Inspect memory (example)
   • q : Quit the debugger
