Command Syntax:

- )show nameOrAbbrev
- )show nameOrAbbrev )operations
- )show nameOrAbbrev )attributes

Command Description: This command displays information about FriCAS domain, package and category constructors. If no options are given, the )operations option is assumed. For example,

)show POLY
)show POLY )operations
)show Polynomial
)show Polynomial )operations

each display basic information about the Polynomial domain constructor and then provide a listing of operations. Since Polynomial requires a Ring (for example, Integer) as argument, the above commands all refer to a unspecified ring R. In the list of operations, $ means Polynomial(R).

The basic information displayed includes the signature of the constructor (the name and arguments), the constructor abbreviation, the exposure status of the constructor, and the name of the library source file for the constructor.

If operation information about a specific domain is wanted, the full or abbreviated domain name may be used. For example,

)show POLY INT
)show POLY INT )operations
)show Polynomial Integer
)show Polynomial Integer )operations

are among the combinations that will display the operations exported by the domain Polynomial(Integer) (as opposed to the general domain constructor Polynomial). Attributes may be listed by using the )attributes option.
