Before you start compiling a program or a series of units, it is important to know where the compiler looks for its source files and other files. In this section we discuss this, and we indicate how to influence this.
Remark: The use of slashes (/) and backslashes (\) as directory separators is irrelevant, the compiler will convert to whatever character is used on the current operating system. Examples will be given using slashes, since this avoids problems on unix systems (such as linux).
