Code examples if( stream == NULL )
Command options -lR
Commands make
Environment variables PATH
File and pathnames /dev/null
Function names exit()

Keyboard keys Enter
Program output login:
Programming constants NULL
Programming data types unsigned short
Programming literals 0xFF, "message string"
Variable names stdin
User-interface components Cancel

We use an arrow (→) in directions for accessing menuitems, like this:

You'll find the Other... menu item underPerspective-->Show View.

We use notes, cautions, and warnings to highlight importantmessages:

Note: Notes point out something important or useful.

Caution: Cautions tell you about commands or procedures that may haveunwanted or undesirable side effects.

WARNING: Warnings tell you about commands or procedures that could bedangerous to your files, your hardware, or even yourself.

Note to Windows users

In our documentation, we use a forward slash(/) as a delimiter in all pathnames,including those pointing to Windows files.

We also generally follow POSIX/UNIX filesystem conventions.
