Hi, as a project i am preparing 8086 assembly language programming emulator. i need help to achieve the following functionalities. 1) I want lines to be numbered as user presses enter key in the textarea. 2) I also want the user to highlight any line in the textarea for the pupose of inserting breakpoints or denoting assemble time errors. 3)I would be preparing a Java source file corresponding to the program entered by the user (during second assembly pass) in this project. Can u tell me how can i automatically compile,run the Java program and simply display the terminal(console) output window to the user, when he clicks the "assemble" button, (without asking the user to manually do all this). I would be really grateful to you if you help me with regard to these problems.
