what does the 21h function do?

    The 21h set of functions is called the DOS interrupt on Intel machines.
    It is actually a collection of a lot of functions and sub functions.
    For example function 01/21h reads a character from standard input.
    Function 09/21h prints a string to standard output. Other functions
    in the 21h collection read/write/open/close files and other basics that
    DOS provides for you.
