(the 'L' in the error number - L210 - also identifies it as a Linker message) Therefore, the Compiler & Linker have both done their stuff. Did they give you any errors or warnings? If so, you must resolve them first*. There's no point trying to resolve Linker errors when the Compiler and/or Linker have already told you that there's problems earlier in the process! Now to the actual message: "PATH OR FILE NOT FOUND; FILE: D1.OBJ"* As I said - just read this literally: it's looking for a file (or path) "D1.OBJ", and it couldn't find it! Obvious, eh?! Presumably, your earlier translations should've created this from one of your source files? So, either they didn't create it, or they put it in the wrong place and/or gave it the wrong name. You can take it from here...

Why did I cite those threads? I said: "As I keep on repeating, you just have to read the message literally" The cited threads merely illustrate the fact that I keep repeating: you just have to read the message literally I then gave you step-by-step instructions on how to do that for one of the messages you gave. Have you followed those steps? Have you found the D1.OBJ file, or determined why it is missing?

Then i asked help me on is code is fault or compiling method problem. on my first post. still i am confused. And i have tried a removing first two lines ie. #pragma SRC, #pragma LARGE and put tick mark for Genrerate asm src file options then compiled. This time ok but warning comes is unresolved external ?c_startup etc. but program works fine. Any way thanks for helping and i am very sorry for taking your valueble time, becasue of i am not expert in c programming and also in ENGLISH LANGUAGE to discuss with other people who knows english only.
