System-specific Text
Although generally operates the same way on all systems, there are a few system-specific differences you need to know about. Where information differs by system, read the information that follows the name of your system, as follows:
UNIX: This text is specific to the UNIX environment.
VMS: This text is specific to the VMS environment
. 
Windows: This text is specific to the Windows environment
. 
The symbol
indicates the end of the system-specific text.
In some instances, system-specific differences are indicated by using parentheses ( ). For example: This is useful for program libraries that are using make dependencies (UNIX) or MMS dependencies (VMS).
