How do you make a white background in a tasm program?

To create a white background in a TASM (Turbo Assembler) program, you typically need to set the video mode to a suitable graphics mode that allows for color manipulation. For example, in 320x200 mode (Mode 13h), you can fill the screen with the color corresponding to white, which is usually color index 15. You can achieve this by using a loop to set all pixels to the white color value. Additionally, ensure to set up the BiOS interrupt for video mode switching before filling the screen.
