The manual is designed to provide quick access to the syntax and usage of each MS-DOS system function, interrupt, and structure. This section describes the information presented on each reference page. A reference page has the following format:
Figure 1.1 Sample Reference Page -- Display Character (Function 02h)
These are the elements shown:
1.The function, interrupt, or structure name. For any function that has been superseded, the word “Superseded” appears to the far right of the function name.
2.The function, interrupt, or structure syntax. The syntax specifies each parameter (or field). It also gives the register that each parameter must be copied to. Comments to the right briefly describe the purpose of each parameter (or field).
3.A description of the function, interrupt, or structure, including its purpose and details of operation. This section may include any special consideration for the function, such as whether the function has been superseded.
4.A full description of each parameter (or field), including permitted values and related structures.
5.A description of the return value or values, including possible error values.
6.A description of special considerations related to use of the function, interrupt, or structure in a program.
7.A list of related functions, interrupts, and structures.
