### Rules for Module Definition Files

When creating a module definition file, follow these rules:

- Use a NAME or LIBRARY statement to define the type of executable output you want. You can only use one of these statements, and it must precede all other statements in the module definition file.
- Begin comments with a semicolon (;). Any line that begins with a semicolon is ignored, as is any portion of a line that follows a semicolon.
- Enter all module definition keywords (for example, NAME and LIBRARY) in uppercase letters.
- Do not use module definition keywords or reserved words as text parameters to a statement (for example, you cannot use the LIBRARY statement to name a library SHARED, because SHARED is a keyword).
