For parameters it is not always mandatory to use the name of the parameter on the command line. In the rest of the definition of the command line syntax, wherever the word qualifier is used, it means both parameters and qualifiers. If parameter is used it will only apply to parameters. Qualifier definition Qualifiers are meaningful words rather than single letters. Qualifiers can be shortened as long as they are not ambiguous.
Qualifiers can appear in any order, although in some cases their scope changes.
Associated qualifiers, specific for a certain data type, immediately follow a parameter of that data type, the qualifier apply only to that parameter and not to all parameters of that data type. This may seem rather confusing, but only because there is no enforcement of a standard recommended way for users to specify the command lines. For general use, we strongly recommend the first example above.
