### Options

Options appear on the command line as mnemonic identifiers prefixed by either of the plus (+) or minus (-) characters, and must be separated from other command line parameters by at least one blank character. Case is not significant in option identifiers.

A single option may be specified more than once on the command line within a given scope; the last occurrence overrides all previous definitions within that scope unless the effect of the option is to collect information in a cumulative fashion. Options are not cumulative unless documented otherwise on an individual basis.

There are two forms of options:

Switch Option
Parameterized Option

Some options may actually combine both functions of the switched and parameterized variations; for instance, the +Fl switch option "turns on" the creation of a listing file, while a parameterized option of the same name (for example, +Fl:george.lst) has the same effect, but also treats the argument field as the name of the listing file to create.
